Abstract : Work pursued was intended to demonstrate the ability of frequency locked bulk effect sources to operate as distributed transmitter sources for a solid state radar system. A module design was evolved consisting of the bulk oscillator, its modulator, a transmit-receive switch, 6 bits of phase control, associated logic circuitry, and a polarization diverse radiator. A linear array of 16 such modules was constructed and evaluated. Additionally, the linear array was utilized as the transmitter-antenna of a solid state phased array radar system. The SPAR system detected stationary targets at ranges up to 11.5 kilometers and light aircraft at 3 kilometers. (Author)
