ABSTRACT:
A test apparatus for the reception channels, e.g. in a doppler radar system with electrically controlled aerial elements (A1-An). Behind each aerial element there are optical detectors (O1-On) arranged for receiving an optical signal from the system transmitter and converting it to an RF signal. The latter is sent to the transmitter-receiver modules (M1-Mn) of the system and further to a detection-measurement unit (3). The measurement unit evaluates the different modules (M1-Mn) with relation to amplitude and phase of the test signal, and sends correction signals to the modules in response to the evaluation. The apparatus can also be utilized for testing the system transmission channels.
