Abstract
In a radar system, a cancellation circuit is described for compensating for the effects of spillover between each transmitter and a receiver. The cancellation circuit is configured for applying cancellation signals to the receiver which are generated in a cancellation filter utilizing a primary impulse response characteristic corresponding to the spillover, a signal to be transmitted from each transmitter in the radar system, and a range profile output from the receiver. The cancellation circuit may also include a secondary impulse response characteristic module and a dithering module to improve the sensitivity of the receiver.
