When a fighter radar detects an air-to-air target with a medium pulse repetition frequency (MPRF) waveform, if the altitude of the platform is low, the air-to-air target detection range is limited by the sidelobe clutter. A high-pulse repetition frequency (HPRF) waveform, which can detect air-to-air targets in clutter-free areas, can be used to remove the air-to-air target detection range limit caused by sidelobe clutter. We present an HPRF waveform design that uses an M-of-N binary integration for the long-range air-to-air target search/tracking mode of a fighter radar. The performance and effectiveness of the designed waveform were confirmed through analysis and fighter radar software-in-loop simulation (SILS) testing.
