Acceleration filter for slowdown discrimination

摘要

A circuit for determining the acceleration of an object being tracked by aoppler radar wherein a part of the received signal is delayed and then subtracted from the received signal to produce a first signal; a portion of the delayed signal is further delayed and then subtracted from the delayed signal to produce a second signal; and the first and second signals are subtracted to produce a signal representative of the acceleration of the object being tracked by the CW Doppler radar.
