脉冲压缩可用来提高发射功率的利用率,并使雷达信号增加同有的电子抗干扰(ECCM)能力。本文研究周期基带相关条件下具有理想副瓣响应的某类三进制序列。利用离散雷达模糊函数来计算周期和非周期调相三进制脉冲压缩序列两者的匹配滤波器响应。列出了三进制脉冲压缩序列、二进制最长序列和弗兰克多相码根据离散模糊函数计算出的数值表,并对它们作了比较,以便说明三进制序列是脉冲压缩雷达的一种极好选择方案。
Pulse compression can be used to increase the utilization of transmitted power and to add the same electronic jamming (ECCM) capability to radar signals. In this paper, we study some kind of ternary sequence with ideal sidelobe response under the condition of periodic baseband. Discrete radar ambiguity function is used to calculate the matched filter response for both periodic and non-periodic phase modulated ternary pulse compression sequences. The triplicate pulse compression sequence, the longest binary sequence and the Frank multiphase code are listed according to the discrete fuzzy function, and the comparison between them is made to show that the ternary sequence is a kind of pulse compression radar Good choice.
