Height Measurement of Micro-UAVs with L-Band Staring Radar

Recently, the staring radar has been developed and used to detect and track micro-UAVs. It shows significant advantages in the surveillance of such slow-moving targets with low RCS for its sensitivities and high Doppler resolutions. Meanwhile, the feature of wide area transmission of staring radar results in multipath effect, especially for low altitude targets. A novel elevation angle estimation approach for staring radar is proposed in order to measure the height of targets. Field trials with micro-UAVs show that the proposed approach can help staring radar to obtain target height parameter accurately.
