  • Dispersed pulse measurement for AGC and dynamic thresholding of a chirped radar receiver
    Patent number: 3973260
    Abstract: Pulse measurement of chirped radar returns is made before dechirping by the se of a linear detector averaging circuits and time delay circuits such that the measurement is indicative of the RMS power of the pulse. Depending on the received chirp pulse different averaging circuits and time delay circuits are switched in so that its output is coincidental with the delayed dechirped signal. Output is encoded for a digital indication of the power and is fed through scalers to set the threshold of the video signal processor.
