Target Localization by Resolving the TimeSynchronization Problem in Bistatic Radar Systems Using Space Fast-Time Adaptive Processor

摘要

The proposed technique allows the radar receiver to accurately estimate the range of a large number of targets using a transmitterof opportunity as long as the location of the transmitter is known. The technique does not depend on the use of communicationsatellites or GPS systems, instead it relies on the availability of the direct transmit copy of the signal from the transmitter and thereflected paths off the various targets. An array-based space-fast time adaptive processor is implemented in order to estimate thepath difference between the direct signal and the delayed signal, which bounces off the target. This procedure allows us to estimatethe target distance as well as bearing.
