FPGA-Based Pulse Compression for Linear Frequency Modulated Signal

Abstract:

Nowadays, compressing linear frequency modulated signals is usually based on DSP and realized by software. It is not only has no advantages on real-time operations but also has high requirements of hardware in processing a multitude of FFT points. Accordingly, we propose a new method to achieve the pulse compression of linear frequency modulated signals through FPGA and simulation results are also promoted. In contrast with using DSP, the new method based on FPGA has a much better performance on reliability, speed and a lower demand of hardware quantity.
