摘    要:雷达频综器在机械条件下由于载机的振动,其输出相噪将严重恶化,从而使动显雷达在杂波下能见度显著变坏,极大地影响地对活动目标的影响。本文以相噪恶化的原因进行了分析,并得出在目前条件下晶振减振仍是唯一可行的避免相噪进一步恶化的有效措施的结论。

关 键 词:机械雷达 频综器 相位噪声 杂波 能见度

Abstract:Because of vibration of aircraft, the phase noise of frequency synthesizer for airborne radar will be worsen, then visibility of MTI radar will be diminished in the background of clutter. In the end it will influence on the detection for movable target. In the paper, the reason of phase noise worse is analyzed. We get the conclusion that isolating crystal oscillator with vibration is still only viable measure to reduce phase noise worse on the present condition.
Keywords:Airborne Radar  MTD  Frequency Synthesizer   Phase Noise  Visibility
