A mini radar system for low altitude targets detection

This paper deals with a mini radar system aimed at detecting small targets at the low latitude. The radar operates at Ku-band in the frequency modulated continuous wave (FMCW) mode with two receiving channels. The radar system has the characteristics of compact, mobility and low power consumption. This paper focuses on the implementation of the radar system and the Block least mean square (Block LMS) algorithm applied to minimize the fortuitous distortion. It is validated from a series of experiments that the track of the unmanned aerial vehicle (UAV) can be easily distinguished with the radar system.
