PROBLEM TO BE SOLVED: To solve the problem of a conventional image radar device that since an image reproduction algorithm for turning observation data into an image is premised on an assumption that a chirp rate uses a certain chirp signal as a pulse signal, the observation data in which the chirp rate changes in the middle cannot be turned directly into an image.SOLUTION: Reflection waves from a plurality of pulse signals from the object of observation that are transmitted at different time intervals are handled as observation data, and the observation data is converted to the waveforms that are equivalent to the reflection waves of a plurality of pulse signals from the object of observation that are transmitted at single time intervals. By applying an image reproduction algorithm to the waveforms generated by this conversion, it is possible to smoothly process image reproduction by using the observation data near boundaries at which a PRF and a chirp rate change. |
