The Design and System Implementation of Multi-parameter Joint Agile Coherent Radar Signal

Advanced deceptive jamming can significantly degrade a radar's detection capabilities and, in severe cases, disable the radar system. Expanding the agility of radar waveform parameters is expected to reduce the effectiveness of jamming parameter reconnaissance, thereby enhancing radar anti-jamming performance. However, complex agile signals pose challenges to the waveform generation of radar systems. Based on this, the paper designs a multi-parameter joint agile radar waveform with low probability of interception. More importantly, it proposes a waveform generation method that meets the real-time requirements of jamming countermeasures. This method involves reading parameters directly from a formatted file, enabling flexible adjustment of waveform parameters and effectively reducing the volume of parameter transmission data. The designed radar signal was implemented on a waveform board card, and test results demonstrate the correctness and effectiveness of the design.
