Abstract : A circuit for reducing the center frequency and bandwidth of microwave signals comprising a source of radar pulses, a Hall element for doubling frequency of signals derived in the circuit is described. The Hall element is connected in the feedback circuit of a comparator amplifier the purpose of which is to provide a difference signal between the radar input signal and the signal from the Hall element. A first RC network is provided at the output of the Hall element to balance the circuit derived signal about zero. A second RC network is provided at the output of the comparator amplifier to balance the output signal from the circuit about zero. The output signal, by action of the circuit elements, is a signal having its center frequency and bandwidth reduced by one half. Means are also provided to cascade circuits and to add radar target simulation to final output signal.
