射频干扰的存在使动目标显示问题大大地复杂化,干扰使动目标显示滤波器产生“瞬时扰动”,从而违成虚警。这一现象在雷达照射目标的相干脉冲串数量有限时就显得特别重要。已研究出一种脉冲射频干扰存在情况下能使动目标显示器有效工作的杂波中射频干扰处理技术(SRP)。这种技术并没有常规“射频干扰检测器”的灵敏度缺口特性。因此,能有效地消除射频干扰引起虚警,而仍保持较好的目标杂波中可见度。这种杂波中射频干扰处理技术已用蒙特卡洛仿真做过分析,并用记录以往的相参雷达信号做过试验。
The existence of radio frequency interference greatly aggravates the display problem of the moving target, and the interference causes the “transient disturbance” of the moving target display filter to violate the false alarm. This phenomenon is of particular importance when the number of coherent bursts targeted by the radar is limited. A radio noise interference processing (SRP) technique for clutter has been developed that can effectively operate a moving target display in the presence of pulsed radio frequency interference. This technique does not have the sensitivity notch feature of a conventional “radio frequency interference detector.” Therefore, radio frequency interference can effectively eliminate false alarms, while still maintaining good visibility in target clutter. This clutter radio frequency interference processing techniques have been analyzed using Monte Carlo simulation, and recorded with the previous coherent radar signal has been tested.
