目前战争中,电子战占居着相当重要的地位。因此,电子对抗技术迅速地发展,雷达抗干扰技术突飞猛进,无线电积极干扰方式多种多样。使电子环境目趋复杂。因此在现代战争环境中,衡量导弹性能优劣的一个极重要的指标就是抗干扰的性能。就目前舰—舰导弹多采用主动雷达寻的制导,也有采用红外、激光、电视制导。它们固然各有其优点,但又各有其缺陷。主动雷达寻的制导,需要借助于舰载雷达探测所攻击目标的位置。众所周知,可用箔丝等假目标的消极干扰方式进行干扰,或用阻塞式等积极(人为)的干扰源进行干扰,探测雷达不能测定目标、导弹无法发射。这需要花费相当大的代价,采用先进的抗干扰措施。另一 In the current war, electronic warfare occupies a very important position. Therefore, the rapid development of electronic warfare technology, radar anti-jamming technology by leaps and bounds, radio positive interference varied. Make the electronic environment more complex. Therefore, in the modern war environment, the measure of the merits of missile performance is a very important indicator of anti-jamming performance. Ship-to-ship missiles on the use of active radar to find more guidance, but also the use of infrared, laser, television guidance. Although they each have their own advantages, they each have their own flaws. Active radar to find guidance, need to help detect the location of the target by the carrier-based radar. It is well known that interfering with the negative interference of fake targets such as foil wire, or interfering with such positive (man-made) interference sources as jamming, the detection radar can not measure the target and the missile can not launch. This takes a considerable price, the use of advanced anti-jamming measures. another
