Research on Quasi-Continuous Wave Radar Signal Based on MAC Sequence

间断连续波雷达信号有效地解决了收发隔离的问题 ,其应用日益引起了雷达界的重视 .本文首先建立了间断连续波二相编码信号的数学模型 ,并在此数学模型的基础上推导了间断连续波二相编码信号的平均模糊函数 ,然后我们采用一种特殊的二元序列———MAC序列 ,对间断连续波雷达信号进行 0 ,π调相 ,最后给出了对该信号性能的计算机仿真结果 .

Quasi-continuous wave radar signal solves the problem of separating transmitting from receiving, and its application arouses the regards of radar community. This paper first establishes the mathematical model of Quasi-continuous wave binary-phase-code signal; then concludes the average ambiguity function of Quasi-continuous wave binary-phase-code signal; later we adopt a kind of special binary sequence - MAC sequence, by which we make 0 and π phase modulation of Quasi-continuous wave radar signal; finally the results of computer simulation of the signal performance are given.
