ABSTRACT:
Interference between two or more radar systems operating on the same freqcy is eliminated by synchronizing the rotation of the scanning antennas. In another embodiment, each transmitter is blanked if the corresponding receiver detects an interfering signal from the other transmitter. In yet another embodiment, the transmitter pulses are not blanked but merely delayed, if a pulse is received from the interfering system.
