ABSTRACT:
A frequency agility radar having automatic electronic front end tuning in synchronism with the transmitter on a pulse to pulse basis is provided. The automatic electronic front end tuning is achieved by the use of a backward wave parametric amplifier. The frequency generated by the radar transmitter is employed to control the center frequency of backward wave amplifier. The backward wave amplifier operates as an electronically tuned filter with the center frequency of the tuner following the radar frequency accurately.
