如今,在信号处理技术飞速发展的背景下,针对传统的雷达信号设计暴露出的功能单一、低截获性能差以及距离速度分辨力较低等问题,构建了 1种基于十三位巴克码的探测干扰一体化信号波形。文中对其调制原理进行了分析,对其中的二相编码序列分量、伪随机码序列分量进行自相关函数特征分析,并分别从模糊函数、功率谱角度分析其探测特性和干扰特性。仿真实验证明,探测干扰一体化信号样式相较于单一调制的十三位巴克码信号具有较好的模糊函数和功率谱特性,在保持二相编码信号良好的多普勒敏感特性基础上,具有更好的距离分辨力以及更 大的干扰带宽。

Design and Simulation of an Integrated Detection-Jamming Signal

Under the background of rapid development of signal processing technology, aiming at the problems of traditionalradar signal design exposed such as single function, poor performance of low interception and low resolution of range and ve.locity, an integrated signal waveform based on 13-bit Barker code is constructed. The modulation principle is analyzed, thetwo-phase coding sequence components and the pseudo-random code sequence components are characterized by autocorre.lation function, and the detection characteristics and jamming characteristics are analyzed from the perspective of ambiguityfunction and power spectrum respectively. The simulation results show that the integrated signal has better ambiguity func.tion characteristics and power spectrum characteristics, better range resolution and velocity resolution, and larger jammingbandwidth compared to the single modulated 13-bit Barker code signal.
