Abstract : This invention relates to doppler radar sets of the type including circuitry for determining and displaying sense of target motion along the radar beam. The Doppler phase shifters in the I and Q channels of pulse radars of this type are designed to operate at frequencies much higher than the Doppler baseband frequencies by selecting one of the Doppler sidebands of the radar's pulse repetition frequency, or one of the sidebands of a harmonic of such pulse repetition frequency, or frequency for application to said Doppler phase shifters. The higher operating frequency simplifies the design and construction of the Doppler phase shifters.
