現代戰争對武器命中精度的要求越來越高,加上信息技術的飛速發展,精確制導武器得到迅猛發展和廣泛應用。精確制導武器在現代局部戰争和衝突中發揮了重要作用,這預示着它即將成爲未來戰争的基本武器。精確制導武器直接命中概率大於50%的制導武器稱為精確制導武器。直接命中的含義是指制導武器的圓公算誤差小于該武器彈頭的殺傷半徑。圓公算誤差(CEP)是指以平均彈着點爲中心,包含50%彈着點的圓的半徑,它是衡量各種精確制導武器能達到的或破壞某一目標需要達到的精度的一種尺度,以米計。
In modern warfare, the requirements on the accuracy of weapon hits are getting higher and higher. With the rapid development of information technology, precision-guided weapons have been rapidly developed and widely used. Precisely guided weapons played an important role in modern localized wars and conflicts, signaling that it is about to become the basic weapon of future wars. Guidance weapons with a direct hit probability greater than 50% are called precision guided weapons. The meaning of a direct hit means that the rounding error of the guided weapon is less than the kill radius of the weapon warhead. Circular Error Calculation (CEP) is the radius of a circle centered on the average strike point and containing 50% of the strike point. It is a measure of the precision that various precision guided weapons can achieve or destroy a target. In meters.
