<p><P>PROBLEM TO BE SOLVED: To acquire a SAR image of high precision at a ground station by using a larger number of observation data pieces than conventionally. <P>SOLUTION: An image radar signal processor comprises: observation means 1 including command reception means 11 for receiving a command from a ground station, target observation means 12 that emits a signal to a predetermined region and receives a reflection signal of the emitted signal from the predetermined region to acquire a reception signal, and air vehicle observation means 13 for acquiring motion data on the air vehicle; high-speed image processing means 3 that according to the command and based on the reception signal and the motion data performs image reproduction processing within a communication enabled time zone, in which observation is performed by the observation means 1, to reproduce a SAR image; small-sized image processing means 4 that according to the command and based on the reception signal and the motion data performs image reproduction processing with higher precision than in the high-speed image processing means 3 by using communication disabled time to reproduce the SAR image; and transmission processing means 5 for transmitting the SAR image to the ground station according to the command. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
