To provide a radar system and a signal processing method which can perform simultaneous observation of a plurality of targets different in direction by a single body, and can acquire a high-resolution image of each target.
In a system in which an aircraft 11 tracks an observation target 4 to make images, a pulse equal to or higher than LPRF is transmitted while a beam 12 is switched over one after another. That is, the beam 12 which is directed to the target ever since it is transmitted, in the present circumstances, is directed for observation to other observation targets located in other directions as well. In an ISAR image analysis, only a reflected wave from the observation target 4 is actually needed, and therefore a reception gate 14 can be made smaller enough than usual PRI 17 for one target by controlling the timing of opening the reception gate 14. Thus, a plurality of targets in many directions can be observed simultaneously by adding a beam control function and a timing control function.
