<p>PROBLEM TO BE SOLVED: To prevent lowering of a speed of signal processing due to data transfer between computing modules, by providing a plurality of computing modules which receive data in a reception signal memory, as inputs, for each beam spot and execute the signal processing. SOLUTION: Radar reception signals are once stored in a reception signal memory 4. Input memories in computing modules 3 are made large enough to receive whole data of one beam spot respectively. According to an instruction of a host controller 1, each computing module 3 receives the radar signal data in the reception signal memory 4, as an input, for each beam spot and executes signal processing. According to this constitution, all the data necessary for the signal processing are closed in one computing module 3 and the signal processing can be performed without necessitating the result of processing by other computing modules 3. Besides, it is possible to eliminate an overhead of processing due to data transfer between the computing modules 3 and to dispense with a common memory.</p> |
