Countdown Frequency Measurement and its Application in Radar AFC

Abstract:

High stability and constant-temperature crystal oscillator as time standard, microcontroller as control core, the countdown frequency measuring electric circuit, rapidly and timely surveying the transmitting frequency during the constant radar transmitted pulse, is a digital frequency measurement module. This module is an important constituent part in digital automatic radar frequency control system, having been successfully applied in a self-adaption frequency control system of meter wave warning radar.
