人们普遍认为现代制导系统可得到比古典比例导航系统更好的性能。然而,这种好的性能是要以元件改进或附加设备为代价的。本文从性能、耐用性和实现的难易三个方面对现代制导系统(MGS)和古典比例导航(PN)寻的导弹制导 系统作了比较。比较一阶脱靶量表明,如果元件允许误差范围能够得到满足,则MGS的脱靶量最小,但若元件允许误差或测量误差变大,则MGS的性能比PN降低得更快,当元件误差或测量误差大到一定程度以后PN比MGS有更小的脱靶量。
It is generally accepted that modern guidance systems achieve better performance than classical proportional navigation systems. However, this good performance is at the expense of component improvements or additional equipment. In this paper, the performance of the MGS and the classical PN navigation system are compared in terms of performance, durability and difficulty of implementation. The comparison of the first-order miss distance shows that the MGS has the smallest amount of miss distance if the allowable error range of the component is satisfied, but the performance of the MGS degrades faster than the PN if the component tolerance or measurement error becomes larger. When the component error or measurement After the error to a certain extent, PN has a smaller miss distance than MGS.
