microwave motion sensor, integrated antenna-oscillator, sensitive area, modulationAbstract
In this work the results of research of microwave motion sensor on the basis of the integrated antenna-oscillator are presented. The option of realization of such sensor with modulation of the electromagnetic oscillations reflected back from the explored object is represented. Influence of the change of frequency of generating oscillations, caused by modulation mode, on forming of sensitive area of the sensor is shown.References
