Abstract

Research results of signal formation peculiarities in autodyne short-range radars with linear frequency modulation by non-symmetric saw-tooth law are presented. Calculation expressions for autodyne signals are obtained in the general case of arbitrary delay time of reflected emission. Temporal and spectral diagrams of autodyne signals are defined in the cases when its period duration is much more than the delay time of reflected emission, as well as for cases when this inequality is not satisfied. Experimental investigations are performed using the autodyne oscillator on the Gunn diode of 8mm-range, which is electronically controlled in frequency by the varicap.
