Problems solved by technology

[0003] Simultaneous system implementation means that radar signals and communication signals use the same waveform or synthesize a waveform through orthogonalization, so that the system has communication functions without affecting the original radar performance; currently existing systems The integrated method of the system is mainly aimed at continuous signals, such as LFM sequences, which affect the communication bandwidth, and the transmitter has a large change, but it will inevitably increase the bit error rate
