The detection principle of aerial targets by ground-based synthetic aperture microwave is outlined. The target detection probability is estimated, and the relationship between the systematic performance and related factors is analyzed in terms of the detection probability. Meanwhile, the feasibility of the aerial targets detected by ground-based synthetic aperture microwave measurement technology is analyzed. The experiments are performed that aerial targets are detected by a ground-based synthetic aperture microwave radiometer. Both theoretical and experimental results show that aerial targets are detected by a ground-based synthetic aperture microwave radiometer is feasibility.
