TARGET SIMULATE EQUIPMENT PROVIDED WITH DELAY LINE FOR TESTING PERFORMANCE OF SYNTHETIC APERTURE RADAR

摘要

[0001] The present invention relates to a target simulator for verifying the performance of ultra-high resolution image radar, and more particularly, to a system and method for verifying the performance of a SAR (synthetic aperture radar) time delay line) to a target simulate equipment (TSE). To this end, the present invention is characterized in that a radio wave radiated from an image radar is received through an RF front end, frequency-down-converted to a baseband, delayed and up-converted by a DRFM, and then finely delayed And a target simulator for sending out the target image to the image radar side. The present invention also provides a target simulator for verifying performance of an ultra-high resolution image radar using a time delay.
