Subsurface radar, SAR and InSAR observation of the moon by means of an HF (5MHz) band FMCW radar onboard SELENE

摘要

Computer simulations have been done in order to present that, in the HF radar observation of lunar surface and subsurface in SELENE project, B-scan analysis enables weak nadir subsurface echoes be detected, and that both SAR and InSAR observations are possible with using a dipole antenna. The mirror image problem in SAR analysis is solved by taking correlation of multiple orbit observations.
