脉压码时间旁瓣的理论研究

The Theoretical Research on Time-Sidelobe of Pulse Compression Codes

本文研究了脉冲压缩码的时间旁瓣的特性，证明了几个定理，并且利用时间旁瓣自身互补定理对６３位ＰＮ码的时间旁瓣作了对消仿真。用这种方法仅需作很少的加法运算，文中还列举实例以说明如何应用文中的定理来减少搜索低旁瓣码的搜索时间。

Some basic properties of the time-sidelobe of arbitrary sequence's auto-correlation function have been studied and several theorems of the time lobe are also proved in the paper.Some practical examples are taken using the theorems. The first example is to search low sidelobe codes,and the second example uses sidelobe's self-complementary property to cancel sidelobe of 63 bit PN code. The method for cancelling sidelobe needs only little add operation.
