| 摘 要： | PRI变换可以有效地用于以TOA参数为标准的PDW分选算法,然而该变换比较复杂,需要消耗大量时间,因此其应用受到限制.通过改变传统PRI变换的运算过程,提出了新的PRI变换算法,可以在很大程度上提高运算速度,而且适用于DSP并行处理,并且不影响其运算精度.通过理论分析和工程实践,验证了这种算法的高效性.

| Abstract: | PRI transform is available to PDW deinterleaving algorithm based on the TOA.However,it needs a lot of time to perform the transform because of the complexity of this method,which leads to the limitation of its application.A new way to perform the PRI transform is presented by which the calculation can be curtailed.The new method is suitable for DSP parallel processing without reducing the accuracy of the processing.Both the theoretical analysis and the engineering practice prove the new method. |
