中国“护卫”(BODYGUARD)激光干扰系统
BODYGUARD LASER COUNTERMEASURES SYSTEM
作者:环球展望军事网编译 来源:今日中国防务网 更新时间:2006-4-26 【字体:

    中国的军事计划者已经承认精确制导空对地武器在现代化战场上的威胁,而且已经研究使用被动和主动干扰方法抑制敌人精确打击武器的可能性。如一个例子,“护卫”(Bodyguard)激光干扰系统被发展去对抗一种特别类型的精确制导武器--激光制导炸弹和导弹。

    虽然它仍然是困难的去知道像“护卫”系统在真正的战斗中的有效性,这种计划反映PLA在准备一个可能的在高科技条件下的局部战争方面多么严重。它也是PLA的传统去使用低价的、简单但有效的方法去对抗敌人的复杂武器系统。它能够预期像这一样的更多的武器系统将会在未来被显示。

    设计特点

    载入到二辆越野卡车和二辆拖车,“守卫”激光干扰系统包括五个子系统,包括激光告警接收机(LWR)、主动激光干扰(ALJ)、被动激光干扰(PLJ)、中央显示控制(CDC)和电源(PS)。一套系统能够保护6,000~16,000平方米的一个面积。

    工作原理

    “守卫”系统将会在目标的附近部署去防护。当敌人的飞机打开它的激光照明对准目标的时候,在目标的周围被展开的激光告警接收机将会探测出激光束而且告知中央显示控制单位。在一秒内被动激光干扰(PLJ)将会发射榴弹在被保护的目标上形成一个烟幕屏障去阻塞敌人的激光照明。

    同时主动激光干扰(ALJ)单位将会发射相似的光束到距防护目标一定距离的假目标上。假目标把激光信号反射回敌人激光种导武器去误导它将会打击假目标而并非一个真正的。

BODYGUARD LASER COUNTERMEASURES SYSTEM

The military planners in China have recognised the growing threat of the precision guided air-to-surface weapons in the modern battlefield, and have been studying the possibility of suppressing enemy's precision strike weapons by using both passive and active countermeasures methods. As one example, the Bodyguard laser countermeasures system was developed to counter one particular type of precision guided weapon -- laser guided bombs and missiles.

Although it is still difficult to tell the effectiveness of systems like Bodyguard in a real combat, this kind of programme certainly reflects how serious the PLA is in preparing a possible local war under high-tech conditions. It is also a tradition of the PLA to use cheap, simple but effective means to counter the enemy’s sophisticated weapon systems. It can be expected that more weapon systems like this will be revealed in the future.

DESIGN FEATURES

Loaded in two cross-country trucks and two trailers, the Bodyguard laser countermeasures system comprises five subsystems, including Laser Warning Receivers (LWR), Active Laser Jamming (ALJ), Passive Laser Jamming (PLJ), Central Display Control (CDC) and Power Supply (PS). One system is capable of protecting an area of 6,000~16,000 square metres.

WORKING PRINCIPLES

The Bodyguard system will be deployed near the target to be protected. When enemy aircraft turns on its laser illuminating to aim the targets, the laser warning receivers deployed around the target will pick up the laser beam and inform the CDC unit. Within seconds the PLJ will launch grenades to form a smoke obstacle over the protected target to block the enemy's laser illuminating.

At the same time the ALJ unit will launch similar laser beam to the fake targets some distance away from the protected targets. The fake targets reflects the laser signal back to the enemy’s laser guided weapon to misguide it so that it will hit the fake target rather than the real one.
