To improve the survivability of fuse, a co-address Multiple Input Multiple Output-Orthogonal Chirp Division Multiplexing (MIMO-OCDM) signal is designed, and a signal processing method of two-phase parametric accumulation is adopted to improve the signal-to-noise ratio of the echo signal. Firstly, the transmission power of a single signal is evenly distributed to each sub-chirp signal of the OCDM signal, and the sub-chirp signals are transmitted by the co-address MIMO radar to reduce the signal transmission power. Subsequently, the first coherent accumulation is carried out on multiple sub-chirp signals received by a single antenna, and the second coherent accumulation is performed on the echo signals received by multiple antennas to significantly enhance the signal-to-noise ratio of the echo signals.
