Abstract
According to aspects of the present disclosure, a radar transmitting power and channel performance monitoring apparatus is disclosed. In one example, such apparatus may include a plurality of couplers, power combiners of multiple stages, and a power monitoring module, wherein the couplers are connected with transmitter/receiver modules of the radar, and each coupler may be configured to collect a transmitting power of a corresponding transmitter/receiver module. Further, the power combiners may be configured to combine the transmitting power collected by each coupler and input the resultant total power to the power monitoring module, and the power monitoring module may be configured to monitor the total power. In addition, aspects of the present disclosure may test an amplitude and phase consistency of the transmitting and receiving channels of each T/R module of radar to ensure the performance of the radar system.
