SPACE SURVEILLANCE

Over the past 35 years the United States has deployed a wide range of systems for monitoring the space activities of other countries.(1) For the most part, the primary mission of these sensors has been to provide warning of strategic missile attack. But the growing number of satellites in orbit has increased the requirement to keep track of new launches and impending decays of satellites, in order to avoid confusing these events with hostile missile launches. In addition, the increasing importance of military space operations has made the tracking and characterization of space systems a significant mission in its own right.

Satellite tracking systems, both optical and radar, are among the most sophisticated and expensive military sensor technologies. Spacetrack radars typically have ranges and sensitivities ten to a hundred times greater than radars for tracking aircraft or surface targets. And optical tracking systems use telescopes that rival all but the largest civilian astronomical observatories. A modest satellite tracking radar or telescope typically costs a few tens of millions of dollars, while the more elaborate radars can cost well in excess of $100 million.

The earliest, and still the least expensive, form of satellite tracking systems rely on sun light reflected off a spacecraft. Visible against the pre-dawn or post-dusk sky, the largest low orbiting spacecraft, such as space stations or imaging intelligence satellites, are of magnitude 0, comparable to the brighter stars in the sky, and many other low-orbiting satellites are visible to the unaided observer.(2) Even satellites at geosynchronous altitudes are visible with relative modest optics, under optimal lighting conditions.(3)

The capabilities of telescopes to observe satellites is primarily a function of the aperture of the primary optical surface of the telescope, as well as the properties of the means used to form the image. Telescopes with mirrors up to four meters in diameter have been used for satellite tracking, while telescopes with meters in excess of eight meters in diameter are used for astronomical applications. Initially, satellite tracking cameras used film systems, but more recently electronic charge-coupled devices (CCDs) have replaced film systems. CCDs provide an instantaneous read-out of the image, avoiding the time-consuming processing required by film systems. These electronic cameras have enabled scientific telescopes of modest apertures of a few meters to obtain recognizable images of large spacecraft in low orbits.(4)

The primary limitation on the resolution of ground-based optical sensors is the turbulence of the Earth's atmosphere. Recently, two new techniques have been introduced to overcome these limitations. Speckle imaging techniques take advantage of the short exposure time of CCDs to produce images of targets with exposure times that are shorter than the time scale of the fluctuations in the Earth's atmosphere, effectively freezing the effects of atmospheric turbulence. Electronically superimposing a number of such images produces a picture of a satellite whose resolution is limited by the capabilities of the telescope itself.(5)

Several other developments in recent years have opened the prospect for greatly improved optical imaging capabilities at significantly reduced costs. New techniques for casting thin mirrors have led to a revolution in optical astronomy, with monolithic mirrors as large as eight meters being produced at significantly lower cost than the four meter mirror that were previously the astronomical standard. Improved construction and control techniques have permitted fabrication of single-aperture telescopes with apertures of up to ten meters. And new aperture synthesis signal processing techniques have permitted the combination of images from multiple apertures to form images that are the equivalent of telescopes with apertures of many dozens of meters.

Although most optical sensors rely on reflected sunlight or emitted infrared energy for satellite tracking, active optical sensors are finding increasingly application. By illuminating a target with coherent laser radiation, these systems can image satellites that are not illuminated by sunlight at night, as well as targets that may be obscured by sky-glow during daylight hours. The use of active illumination also permits direct measurement of the range to the target, as well as facilitating characterization of the satellite's structure.

Ground-based radar systems have been used since the late 1950s to track civilian and military satellites.(6) Radars have several advantages over optical tracking systems, including the ability to observe targets 24 hours a day, and during cloudy or overcast conditions. Today the United States and the Commonwealth of Independent States both deploy extensive networks of radars which perform the satellite tracking function, as well as other duties, such as detection of missile attack. The performance of a radar is a function of the range to the target and the target's size or radar cross-section, as well as the radar's transmitting frequency and power, and the diameter of the transmitting antenna. Radars used for the initial detection of targets typically are able to locate an object with an accuracy of about 1,000 meters, while tracking radars have accuracies of from 10 to 300 meters.(7)

As radar technology has advanced, the problem has taken on a new dimension. Today's modern and sophisticated large phased array radars (LPARs) can serve many functions. They can provide early warning of missile or bomber attack. LPARs can track satellites and other objects in space and observe missile tests to obtain information for monitoring purposes. They are also an essential component of present generation ABM systems, providing initial warning of an attack and battle management support, distinguishing RVs from decoys, and guiding interceptors to their targets. In some cases, distinguishing an LPAR designed for one of these functions from one designed for an ABM role can be rather difficult.

62301E Strategic Technology

ST-2 Space Surveillance TEAL AMBER

Although most optical sensors rely on reflected sunlight or emitted infrared energy for satellite tracking, active optical sensors are finding increasingly application. By illuminating a target with coherent laser radiation, these systems can image satellites that are not illuminated by sunlight at night, as well as targets that may be obscured by sky-glow during daylight hours. The use of active illumination also permits direct measurement of the range to the target, as well as facilitating characterization of the satellite's structure.

American systems of this type include the Teal Amber laser radar at the Malabar Optics Laboratory in Florida, which has a total of three optical tracking receiver systems, and eight laser transmitters.(30) Others include the LARIAT (Laser Radar Intelligence Acquisition Technology) system at Cloudcroft, Arizona, and the 60 centimeter aperture Teal Blue laser radar is operational at the AMOS facility on Mt. Haleakala in Hawaii.

62301E Strategic Technology

ST-8 Space Object Identification AMOS

The Maui Optical Tracking and Identification Facility (MOTIF) is located at the Air Force Maui Optical Site (AMOS) on Mount Haleakala in Hawaii. MOTIF includes a pair of 1.2 meter surveillance and tracking visible light and infrared telescopes, which operate at ranges of over 35,000 kilometers.(31) AMOS is host to one of the operational GEODSS stations. In addition, a 1.6 meter aperture telescope is used to provide 0.3 meter resolution images of satellites at ranges of over 750 kilometers, with tracking capabilities up to 35,000 kilometers, using reflected visible light and infrared.(32)

Currently planned AMOS upgrades include installation of a 4 meter telescope, designated Advanced Electro-Optical System (AEOS).(33) Advanced research is currently under way that could eventually lead to an even more capable system, applying synthetic aperture techniques to combine the images from nine 2-meter diameter telescopes to provide images equivalent to those of a 12-meter telescope, at a cost of about $20 million.(34)
