ABSTRACT:
In a radar sensor, a continuous microwave signal is passed through an RF switch which is periodically controlled by a pulse signal. The pulse signal is frequency modulated in such a way that the spectrum of the pulse signal is expanded without decorrelation occurring. Using this arrangement, the noise level is kept low and the detection range is increased.
