Development of Millimeter-wave FMCW Vertical-looking Entomological Radar System

This work presents a frequency modulated continuous wave (FMCW) millimeter-wave vertical-looking radar (VLR) system. The proposed system operates at 34.5 GHz and can continuously detect targets flying at a maximum of 200m above the ground. In field tests, it measures the target's displacement direction, moving speed, mass and body shape. An Altera Stratix IV FPGA is utilized for signal processing of the FMCW radar signal. A cosecant squared pattern leaky wave antenna is suggested to detect the targets with constant power and reduce the data processing load in real time system.
