Abstract :
This paper addresses a method for the design and processing of a hybrid signal for low-flyer detection. We combine the LFM (linear frequency modulation) signal and random hopped frequency signal together to form the hybrid signal, which possesses high-range-resolution (HRR) ability and better ECCM character. In the course of the signal processing, a two-stage pulse-compression technique is applied in order to get the range resolution less than 10 cm. Finally, the paper gives the actual experimental result that proves the correctness of the method
