Abstract
A radar receiver for a frequency-agile radar system includes a variable frequency oscillator and an automatic frequency control operable to exert fine control over the frequency generated by the local oscillator. Control means are provided to derive from a number of previous values of the local ocillator frequency a control signal for application to the local oscillator to bring the generated frequency close to that required for fine correction by the automatic frequency control.
