<p>PROBLEM TO BE SOLVED: To solve problem of increase in data rate degradation of image quality, decrease of observation width, lowering of correlation between images, etc. SOLUTION: A transmitter So outputs transmission waves 1 and 2 with different chip modulations with a time shift. The transmission waves 1 and 2 are transmitted from antennas Al and A2, simultaneously receives reflection waves 1 and 2 with an antenna 1 and outputs selected wave to a receiver J1. The receiver J1 records the reflection waves from the antenna A1 as SAR (synthetic aperture reader) data. An interferometry SAR reproducer 1F performs two kinds of SRA reproducing process corresponding to each of chirp modulations of transmission waves 1 and 2 outputted by the receiver J1, so that two SAR images (complex data) corresponding to the reflection waves 1 and 2 are reproduced from one SAR data and makes them interfere.</p> |
