Patent attributes
A radar transducer has a planar array antenna mounted on a plate portion of a housing with the microwave transceiver mounted on the opposite side of the plate and carrying a PCB defining the processing section for supplying an output to a cable. The plate portion slides into a plastic receptacle defining the radome for the antenna with a potting compound sealing the open face of the receptacle. The electrical processing section is shielded from extraneous electromagnetic waves without additional metallic shielding elements. The processor is programmable in response to signals received through the output cable so as to re-configure the program thereof so as to change the output to the output cable for different end use controllers and for compatibility with communications protocols. The processor is programmed to carry out a test of the operation of the transceiver and to provide a failure output signal to the cable in the event that the operation is found to be outside predetermined parameters.
