针对认知雷达中的发射波形设计问题,给出了一种基于对非均匀杂波感知的自适应发射波形设计方法。该方法利用正交波形对杂波信息进行感知,在多目标场景中建立最大化最小输出信杂噪比的数学模型,并采用半正定规划(SDP)算法对其求解。仿真结果表明,该方法较准确地获得杂波功率在空间分布的信息,模型得到的最优发射波形有效地提高了输出信杂噪比,增强了雷达在复杂环境中的生存能力。
Abstract：Aiming at the problem of transmitting waveform design in cognitive radar,this paper proposes a design method of adaptive transmit waveform based on inhomogeneous clutter sensing. This method uses the orthogonal waveform sense the clutter information,and set up the mathematical model of maximizing the minimum output signal-to-clutter-plus-noise ratio( SCNR) in multitarget scenario,which can be solved by Semi-Definite Programming( SDP).The simulation results show that the method can obtain the information of the clutter power in spatial distribution more accurately and the optimal transmit waveform from the model can effectively increase the output SCNR,which improves the radar survivability in the complex environment.
