Method for increasing noise resistance of radar sensors with frequency selection

The description of a new method signal generation and processing which provides an increase in the noise immunity radar sensors (RS) with frequency switching (FS) radiation is presented. principle use set time intervals when measuring phase difference signals at different frequencies and, accordingly, Doppler values spectrum determining average value frequency, as well forward reverse IF sequences. This allows averaging results calculating individual implementations thereby, accuracy target speed distance to it. At same time, stability RS FS also increases effects from third-party radio sources interference underlying surface. experimental studies are obtained on example autodyne 8-mm range, made basis Gann diode generator control by varicap. may be used on-board (for example, automotive) designed detect moving targets, measure them, determine direction movement.
