Abstract
An automatic thresholding reference and detection circuit which generates a signal in time which is a replica of the radar return signal's doppler spectrum. The radar signal return is processed by a target signal channel having a narrow bandwidth filter which produces a fine resolution replica of the signal spectrum, and by a reference signal channel having a wider bandwidth filter, which produces a smeared (or average) replica of the signal spectrum. The output of the reference signal channel is a threshold signal which, when compared to the output of the target signal channel, allows only the target signals to be passed for further processing and rejects clutter and thermal noise.
