摘要：

Orbital debris with dimensions between 1 and 10 cm is an increasing threat to the Space Station Freedom. A possible solution is to track the debris with a station-based radar and passive IR sensors. Studies at JSC have shown that the approach window of the debris is relatively narrow, +/-10-degrees in elevation and +/- (30-degrees to 90-degrees) in azimuth. preliminary JSC studies suggest that angle and range accuracies of 10(-4) radians and 6 m are required for trajectory determination. Design considerations for minimizing the costs of a microwave array antenna are discussed. A proposed ground-based radar/antenna experiment for tracking small particles with high angular rates is described.
