Pulse Compression Processing of Biphase Coded Signals

In the referenced example ex9_12, we can perform pulse compression processing on biphase coded signals. For radar biphase coded pulse compression applications, we utilize a 13-bit Barker code. The Barker code possesses excellent autocorrelation function characteristics, which results in superior pulse compression performance. By implementing Barker code-based pulse compression processing, we can effectively enhance radar system performance through matched filtering techniques that optimize signal-to-noise ratio and resolution. The algorithm typically involves generating the Barker code sequence, applying it to modulate the radar pulse, and then performing correlation processing at the receiver using a matched filter implementation. Key functions would include code generation, convolution operations for compression, and peak detection algorithms to identify compressed pulse outputs. The 13-bit Barker code specifically provides good sidelobe suppression properties with a peak-to-sidelobe ratio of 22.3 dB, making it ideal for radar pulse compression applications.
