| 1. | The designing of an early - warning system of missile has difficulties because it needs smaller mass , great rigidity , high strength as load on the satellite . it also needs real - time tracing and a pointing and tracking system with stationarity , rapid rotation and high precision
设计导弹预警系统难点在于:作为星上载荷,要求质量小,刚度、强度大,要实现实时跟踪目标,要求指向跟踪系统转动平稳、快速,精度高。 |
