Patent ID: 8886134

Claim:
Method for monitoring the integrity of a Doppler transceiver, said Doppler transceiver includes a transmitter unit which includes a transmitting antenna, a receiver unit which includes a receiving antenna, at least one mixer unit, a processor unit, and, a signal transmitted from said transmitting antenna of said transmitter unit, comprising the steps of: transmitting, using said transmitting antenna, partially, said transmitted signal into a modulation unit using a transmitted signal path, said modulation unit integrated between said transmitting antenna and said receiving antenna; said processing unit triggering said modulated signal utilizing a separate path other than said signal path between said transmitting antenna and said modulation unit; modulating said transmitted signal according to certain parameters; transmitting using said modulation unit said modulated signal back to said receiving antenna of said receiver unit; mixing said received signal and said transmitted signal in said mixer unit to detect signal modulation; and, processing said modulated signal in said processing unit and classifying said modulated signal as a correct response of said transceiver under applied calibrated stimulation.
