摘要
根据雷达和通信功能综合化方式,归纳出雷达通信综合化波形设计的三类途径,并按此分类介绍了已有的各种设计方案。分析发现,上述方案主要存在三种问题:一是波形携带通信数据的能力差,通信速率低;二是波形具有调幅特性,经雷达C类放大器发射后影响通信性能;三是波形接收时必须滤除通信分量,损失接收功率,进而损害探测性能。为解决存在的问题,文中提出基于MSK调制LFM脉冲的新型雷达通信综合化波形。该波形由在雷达常用LFM脉冲上采用MSK方式调制通信数据而得。波形包络恒定,相位连续,C类放大不影响通信性能。其波形模糊函数较LFM脉冲更接近图钉型。
According to integration schemes, achieved three design approaches to Radar-communication integrating waveform. Intro- duced and analyzed those proposed solutions of radar-communication integrating waveform and found that those solutions mainly suf- fered from three problems. The one was poor capacity communication message of some waveforms, thus could not meet the require- ment of high speed communication. The second was that some waveforms carried message by amplitude modulation （AM） scheme, which would lessen the communicaiton performance when these waveforms were transmitted through the C-class amplifier of radar. The third was that some waveforms had to remove the component of communication when processing in radar receiver, which would evidently impair radar receiving power. To overcome these defects, a novel radar-communication integrating waveform was proposed. The waveform was derived from modulating data onto LFM pulse by MSK scheme. The waveform has constant envelop and continuous phase, suited to C-class amplifier of radar. The ambiguity function of the waveform was more closed to nail shape.
