ABSTRACT:
An improved radar system utilizing the principle of nonlinear contact effects for detecting and identifying a target, includes two radar transmitters (12,16) at least one of which is a baseband pulse radar transmitter. Both transmitters illuminate the same target and the signals from each transmitter are mixed in a nonlinear junction (40) of the target. Mixing the two signals provides a target return signal whose frequency spectrum contains cross product frequency components having high resolution target data due to the broad spectral content of the baseband pulse, and thus provides a system capable of detecting and identifying the illuminated target.
