歷史

[编辑]

MR-500雷達於1956年開始發展,基本架構來自蘇聯海軍使用的Kaktus雷達,1957年進入服役,安裝在卡辛級驅逐艦(Kashin Class)上,除了蘇聯海軍以外,也外銷到印度。這是蘇聯最後一款大型2維對空長程搜索雷達。

性能特點

[编辑]

MR-500採用可調節磁控管(Magnetron)產生訊號,行波管(TWT)用以放在回波,使用L-波段,對空中目標的偵測距離為270公里(對500公尺飛行高度的戰鬥機或是中型轟炸機),或是300公里(對飛行高度13公里的Yak-25攔截機)。最短偵測距離估計為0.9公里,天線轉速6.7到8.6轉/分。

為了對抗噪音干擾,MR-500雷達能夠在2至3秒以內將操作頻率切換到預設的5個頻率之一,以避開干擾訊號的影響。此外,為了降低盲速範圍,雷達的發射單元可以產生兩種不同的脈衝重覆率(PRF)。
