Abstract

Cognitive radar is an intelligent system, and it can adaptively transmit waveforms to the complex environment. The intelligent radar system should be able to provide different trade-offs among a variety of performance objectives. In this paper, we investigate the mutual information (MI) in signal-dependent interference and channel noise. We propose a waveform design method which can efficiently synthesize waveforms and provide a trade-off between estimation performance and detection performance. After obtaining a local optimal waveform, we apply the technique of generating a constant modulus signal with the given Fourier transform magnitude to the waveform. Finally we obtain a waveform that has constant modulus property.
基于恒模约束的多雷达任务自适应波形设计
认知雷达是一种智能系统,能够对复杂环境进行自适应的波形传输。智能雷达系统应该能够在各种性能目标之间提供不同的权衡。本文研究了信号相关干扰和信道噪声中的互信息。我们提出了一种波形设计方法,可以有效地合成波形,并提供了估计性能和检测性能之间的权衡。在得到局部最优波形后,对该波形采用给定傅里叶变换幅度的恒模信号生成技术。最后得到了一个具有恒模特性的波形。
