Abstract
The behavior of Doppler RADAR with self-detecting diode oscillators is described. Conditions for the frequency deviation to contain only the first harmonic of the Doppler shift frequency are given. The conversion gain and the signal-to-noise (S/N) ratio includlng both intrinsic LF and RF noise are calculated. An equivalent LF circuit is obtained. The shape of the I-V characteristic of the oscillating diode is shown to be important for the design of a Doppler module.
