Simulation of pulse compression performance under influence of background noise in modern surveillance radar

In this paper, simulation of pulse compression performance in radar systems under influence of Gaussian noise and low angle Weibull land clutter have been presented. Peak side lobes (PSL) of optimized biphase pulse compression codes (OBPCC) of lengths ranging between 5-30 have been discussed. Optimization of peak side lobes is processed using Genetic algorithm optimization tool. Simulation of pulse compression performance at signal to noise ratio (S/N) varying between 5 to 30 dB is introduced. Comparative study shows that for low values of S/N, the peak side lobe level for OBPCC under influence of background noise is equal to its correspondence of ideal biphase codes used in pulse compression radar, leading to enhancement of detection capability, range resolution and compression ratio of modern surveillance radar systems.
