Abstract
A bi-static radar system with an autonulling feature. The system may be used to detect clear air turbulence, for example, in the vicinity of the airports, or to provide an electronic fence for moving air-borne targets having low radar cross sections. The receiver comprises signal and nulling antennas, and the signal received by the nulling antenna is electronically adjusted in phase and amplitude to provide autonulling of the background signal received directly from the transmitter.
