摘要
高频雷达系统中,远距离扩展杂波经距离折叠后,将淹没检测区域中的目标,为保证目标的检测质量,需对折叠杂波进行抑制。在发射二重波形重复频率信号下,提出了通过逻辑映射抑制杂波的方法。给出了参数设计准则,并分析了算法对杂波的抑制性能。仿真实验表明,在合适的信号参数下,该算法能够有效地抑制远距离折叠的扩展杂波。
In the high-frequency radar system, the target of interest might be merged in the range-folded clutter. To get better detection performance, the range-folded clutter need to be suppressed. A logical-mapping clutter suppression method using dual waveform repetition frequency （WRF） is proposed. The selection criteri- on of signal parameters is given and the clutter suppression performance is also analyzed. Simulation results sug- gest that the clutter can be efficiently suppressed under proper signal parameters.
