Abstract
A pulse coherent Doppler radar allows both transmission frequency agility and pulse repetition frequency agility in association with phase encoding which accomplishes the transmission frequency agility by the use of a transmission oscillator, the nominal frequency which may be modified by a microcomputer, a local oscillator, a reference oscillator, and a phase-locked loop having a phase comparator with the oscillator and a mixer for receiving the signals issued by the oscillator and the signal issued by the local oscillator.
