SINGLE TIME SHARED RECEIVER AND FREQUENCY TRACKER FOR A BEAM-LOBED DOPPLER RADAR SYSTEM

摘要

A single time shared receiver and frequency tracker for a beam lobed Doppler radar system. The returns from the fore and aft beams, which are radiated simultaneously are separated through a process of mixing and filtering to obtain two signals which when summed will provide the fore signal and when differenced the aft signal. The sum and difference are alternately sampled and provided to the freqency tracker which includes means to separately store each of the four Doppler system frequencies.
