Abstract
When an excitation signal is generated from an exciter due to an activation signal generated from a radar control device and is distributed to supply to each antenna sub-module, a combination reception signal is transmitted to a receiver from each antenna sub-module. The receiver takes in the combination reception signal obtained by each sub-module in response to an instruction from the radar control device, a frequency converter converts the combination reception signal into a prescribed frequency band, and a distributed aperture combination circuit performs a beam combination in accordance with a distributed aperture combination algorithm. In this way, a radar apparatus, which is equivalent to an active phased array radar of a large aperture and with high performance, is achieved.
