<p>A method for testing a pulse Doppler radar sensor circuit comprising at least one antenna, and a switch circuit, comprising the steps of 1) configuring said switch circuit such that a first path between an input terminal and a first output terminal and a second path between an input terminal and a second output terminal introduce different phase delays to an input signal; 2) providing an input signal to the switch circuit at said input terminal; and 3) comparing a signal at the first output terminal and a signal at the second output terminal to determine if the sensor circuit is functioning.</p> |
