FREQUENCY SHIFT RATE DETECTOR

摘要

Aabstract of the Disclosure The invention disclosed relates to a doppler shift rate detector system for detecting the presence of doopler signals exhibiting small magnitudeo of frequency shift rate. The primary application of the novel detector system is in the detection and identification of hellistic missiles which employ radial command - doppler type guidance systems. By means of relatively simple circuitry the novel device is capable of solving the intercept problem over a relatively wide frequency band in the absence of reference frequency.
