Matched Filtering of Radar Multi-Pulse Echoes

After processing radar multi-pulse echoes through matched filtering, we can further implement coherent integration to effectively improve the detection signal-to-noise ratio. Coherent integration is a signal processing technique that reduces noise impact by performing weighted accumulation of multiple echo signals, thereby increasing detection reliability and accuracy. In implementation, this typically involves phase alignment using Doppler compensation and coherent summation across multiple pulses. This method is widely used in radar signal processing applications and can significantly enhance radar system performance. Therefore, in radar signal processing workflows, we should fully leverage coherent integration technology to achieve superior results. The process generally includes pulse compression through matched filtering followed by coherent integration across multiple periods, which can be implemented using FFT-based Doppler processing and phase-sensitive accumulation algorithms.
