本文把防空导弹系统对目标的探测和对导弹的制导相提并论,是因为尽管制导对防空导弹十分重要,但是防空作战离不开目标探测。尤其是随着空中威胁和战场环境的日益复杂化,目标探测越加困难。目标探测制导技术对防空导弹的发展起着越来越重要的作用。探测制导技术的发展变化取决于防空导弹将要面临的战场环境和将要对付的空中威胁。 This article compares the detection of air defense missile systems with the guidance of missiles because, although guidance is very important for air defense missiles, air defense operations can not do without target detection. In particular, as air threats and battlefield environments become increasingly complex, target detection becomes more difficult. Target detection guidance technology plays an increasingly important role in the development of air defense missiles. The development of detection guidance technology will depend on the battlefield environment that air defense missiles will face and the air threats to be dealt with.
