Abstract

An improved local oscillator arrangement for a monopulse receiver in a semiactive missile guidance system is shown. The monopulse receiver includes an improved reference local oscillator wherein a first local oscillator signal and a pair of reference signals required to demodulate the output of the intermediate frequency section of such receiver are derived simultaneously from the output of a single voltage controlled crystal oscillator. The frequencies of the first local oscillator and the pair of reference signals are related to the frequency of the radar modified by any Doppler shift frequency experienced during an intercept.
