| 摘 要： | 针对宽波束方式的线性调频高频地波雷达在海洋硬目标探测中会把编队多目标识别成点目标的问题,提出了线性调频高频雷达的虚拟跳频模式,给出了跳频间隔的选取以及幅度和相位补偿的原则,并在线性调频高频地波雷达中,对其回波信号采用虚拟跳频的处理方式来提高编队目标分辨能力.实验结果证明,这种虚拟跳频的处理方式能够改善角分辨力,对线性调频的高频雷达具有重要的工程意义.

| Abstract: | To distinguish formation targets with wide-beam HF radar,this paper presents a selection of frequency hopping interval and amplitude and phase compensation principle,and the echo signal is obtained by virtual hopping approach to improve the ability to detect the target formation in the linear FM high-frequency ground wave radar.The experiment results proved that the virtual hopping approached computational overhead,and with good correlation to the performance it improved angular resolution and range resolution.The linear frequency modulation high-frequency radar has important practical significance in the project. |
