Helicopter-borne mtd radar development and flight test for moving clutter measurement

Helicopter-borne multi-mode radar experimental model has been developed for air surveillance and navigation mission study. In this paper, the radar system is designed and implemented with the key system and subsystem specification, and the various field tests are conducted for performance evaluation. Key subsystems are the planar array antenna, coherent transceiver, and multi-DSP based radar signal processor for pulse compression, MTI and MTD, CFAR, and compensation processing of shifted clutter spectrum. Through the helicopter-borne radar flight test using real-time radar data acquisition system, the Doppler shift of clutter spectrum due to the platform motion is measured and analyzed in terms of the various operational parameters.
