Abstract
A target tracking airborne active radar system in which a reduction in transmitter power is achieved by using individual amplifiers in the aerial quadrant channels. The amplifiers provide gain on transmission and negligible loss on reception and are realized by Impatt diode/hybrid junction modules.
Claims9
A radar system comprising a multi-channel transmit/receiver aerial system, comparator means for providing sum and difference channels for target detection, a low power radar transmitter, means for coupling said radar transmitter into the sum channel, a radar receiver, means for coupling said sum and difference channels to the radar receiver, amplifying means individual to each of the aerial channels, said amplifying means being controllable to provide high gain in the transmitting direction and negligible loss in the receiving direction, and control means for switching said amplifying means, said means for coupling said transmitter, and said means for coupling said receiver, in accordance with pulsed operation of the radar system.
