现代战争越来越多地采用低空或超低空袭击目标,尤其是海战中,飞机、导弹常常采用贴近海面飞行(理想的飞行高度离海面为15米)来逃避雷达探测。西欧有一种海掠式反舰导弹,飞行高度离海面仅有3—5米,舰载炮瞄雷达要探测和跟踪贴近海面飞行的飞机和导弹是十分困难的,而且雷达易受敌方电子干扰,尤其是容易遭受敌方反雷达导弹攻击。舰用光电跟踪仪正是在这种实战要求下迅速发展、逐步完善起来的。法国舰用光电跟踪仪的发展比较迅速,型号有十余种,大体可分两类:第一类是雷达和电视组合起来的装置,如“织女星”系统,第二类是电视、红外跟踪头和激光测距仪组合起来的装置。
In modern warfare, targets are increasingly being used to attack at low or very low altitude. Especially in naval warfare, aircraft and missiles often evade radar detection by being close to the sea (the ideal flight altitude is 15 meters above sea level). In Western Europe, there is a sea-swept anti-ship missile with a flight altitude of only 3-5 meters above sea level. It is very difficult for a shipborne aiming radar to detect and track aircraft and missiles flying close to the sea, and the radar is vulnerable to enemy electronic interference , Especially vulnerable to enemy anti-radar missile attacks. Ship photoelectric tracking device is the rapid development of this actual combat requirements, and gradually improve. France ship photoelectric tracker developed rapidly, there are more than 10 models, generally can be divided into two categories: The first is a combination of radar and television devices, such as “Vega” system, the second category is television, infrared tracking head And laser range finder combination of devices.
