Abstract

A radar system for discriminating between sources of radar interference and targets of interest. The system includes a transmitter for transmitting radar signals into a region, a receiver for receiving return signals of the radar signals returned from within the region, and a processor for processing the return signals to discriminate between return signals returned from a first object and return signals returned from a second object where the return signals from the second object comprise both zero and non-zero Doppler components and interfere with the return signals from the first object. The radar system is operable for discriminating between the return signals when the return signals are received at a distance from the second object which is less than a proximity limit based on the geometry of the object.

Claims

1. A radar system for discriminating between sources of radar interference and targets of interest, the system comprising:

means for transmitting radar signals into a region;

means for receiving return signals of said radar signals returned from within said region; and

means for processing the return signals to discriminate between return signals returned from a first object and return signals returned from a second object wherein said return signals from said second object comprise Doppler components and interfere with said return signals from said first object;

wherein said radar system is operable for discriminating between said return signals when said return signals are received at a distance from said second object which is less than a proximity limit based on the geometry of the object.
