摘要
讨论了合成孔径雷达 (SAR)距离向数字脉冲压缩的原理和实时实现技术。以TMS32 0C6 70 1和APEX2 0K系列EPLD为例 ,叙述了针对不同SAR系统参数的频域和时域的实现方案。其中包括快速卷积重叠保留法的TIDSP实现 ,以蝶形运算核实现FFT为主要技术的EPLD实现等频域实现方式 。
We discuss the theory and real time realization of the digital pulse compression of the synthetic aperture radar (SAR). With TMS320C6701 and APEX20K EPLD as examples, we study the different schemes realized in frequency domain or time domain for different SAR system parameters. The schemes include the TI DSP realization of quick convolution by overlapping-reserving method, the realization of EPLD whose main technology is FFT implemented by butterfly operation core, the time domain realization with the FIR convolution architecture, and the applicability of these schemes.
