Patent Images
1. A polystatic correlating radar apparatus for detecting and locating an object, comprising at least means for transmitting a radar signal;
- a plurality of radar signal receivers, including means for correlating said transmitted radar signal with a received signal for range gating said received radar signal for determining the range of said object from said receiver;
means for cross correlating the radar signal received by each of said plurality of said receivers with each said receiver to provide corrected received radar signals from all of said receivers;
signal processing means in electrical communication with said means for cross correlating said radar signals, for determining the angular location and the radial range of said object from said receivers;
wherein said signal processing includes means for determining the tangential velocity of said object relative to said receivers.

Abstract
The polystatic correlating radar includes a plurality of radar receivers which receive a signal reflected from an object from one or more radar signal transmitters. Signals received from the plurality of receivers are cross correlated to provide high resolution of the angular location, range, and radial velocity measurements, as well as tangential velocity measurements for close targets.

5. A method for correlating polystatic radar for detecting and locating an object, comprising the steps of:
-
transmitting a radar signal; receiving said radar signal reflected from said object at a plurality of receivers, and range gating said received radar signal from each of said receivers; cross correlating the receiver signal output between each of said receivers; and processing said cross correlated receiver outputs to determine the angular location and range of said object; further including the step of determining the tangential velocity of said object responsive to said cross correlated receiver output. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
