A synthetic aperture radar signal processing device is provided with a high-accuracy coefficient calculation unit 7 that, if a determination is made by a determination processing unit 6 that an error has deviated from an acceptable range, calculates the distance R from a mobile platform to a pixel position (a, b) within an observation target corresponding to an assumed position (xt, yt) and a phase coefficient A using a high-accuracy calculation method and a low-accuracy coefficient calculation unit 8 that, if a determination is made by the determination processing unit 6 that the error is within the acceptable range, calculates a distance R' from the mobile platform to the pixel position (a, b) within the observation target corresponding to the assumed position (xt, yt) and a phase coefficient A' using a low-accuracy calculation method (for example, a calculation method using approximation). |
