| 摘 要： | 基于噪声与杂波背景下,雷达对微弱目标探测的波形优化问题,以最大化目标回波信干噪比(SINR)为准则,结合相位调制与最优发射接收波形优化方法(OTRD)的各自技术优势,在相位调制信号的基础上进行最优调幅,提出了一种基于相位调制与OTRD的综合雷达波形设计方法。通过仿真,得到了相较于前2种算法更大的SINR,特别在较强的杂波环境下,对低可探测目标的探测中,效果尤为明显,雷达的探测性能得到了显著提升。

| Abstract: | The radar waveform design for weak target detection in interference and channel noise is considered. Based on the principle of maximizing the SINR, combined with the advantages of the phase-modulate method and the Optimum Transmit-receive Design method (OTRD), a synthesized waveform design method based on phase modulate and OTRD is put forward. Through the simulation, a larger SINR is obtained compared to the previous two methods, the effect is particularly obvious for weak target detection in strong interference, consequently, the function of radar detection is promoted obviously. |
