摘要
基于对经典线性调频步进信号频域合成宽带算法及运算量的分析,针对频域合成宽带算法处理速度有待提高和工程应用的局限性,文中对算法进行了优化改进,提出了一种新的频域合成宽带的快速算法。该算法通过优化处理流程、降低处理点数,减少了运算量,提高了处理效率。该算法性能与经典频域合成宽带算法一致,且无需专门设置雷达参数,实现了频域合成宽带算法工程应用。
To overcome the disadvantages of low speed and limitation of the traditional frequency domain synthetic wideband algo- rithm in engineering application, based on analyzing its algorithm and calculation of stepped-frequency chirp signal frequency pro- cessing, a new fast frequency-domain synthetic wideband algorithm is proposed by optimizing the traditional one in this paper. The new fast algorithm reduces the calculation and improves the efficiency of the traditional one through optimizing procedures and cut- ting down processing points. The fast algorithm has excellent performance in accordance with the traditional algorithm, and it needn＇t to set special radar parameters, and finally realizes engineering application.
