当出现大目标回波时,在脉冲多普勒雷达系统中相位噪声的重要性(杂波中的能见度)由系统所要求的动态范围来确定。振荡器的相位噪声可能掩盖出现在大型固定目标附近的小型活动目标,并削弱雷达的检测能力。识别这种目标是极为重要的,因为在实战中通常都有雷达监视着含有坦克(感兴趣的小型活动目标)的地面情况(大型固定目 The importance of phase noise (visibility in clutter) in pulsed Doppler radar systems is determined by the dynamic range required by the system when large target echoes occur. The phase noise of the oscillator may mask small moving targets appearing near large fixed targets and impair the detection capability of the radar. It is extremely important to identify such a target because in practice there are usually radar monitors of the ground that contain tanks (small-scale activity targets of interest) (large fixed-head
