摘要
介绍了一种应用于导弹近距探测领域的毫米波系统,它综合采用多体制复合调制、中频数字化、频域信号处理技术和自适应抗干扰技术,提高了系统抗干扰性能,并具有了智能化、可编程的特点。它能够根据战场目标/环境/干扰的变化情况,在弹道上自适应选择有针对性的调制方式及最佳工作模式,以达到最佳抗干扰的目的。文中介绍了系统构成、关键技术及其实现方式,并指出了它的工作特点和应用前景。
A millimeter-wave system used in missile short range detection field is introduced. To improve antijamming performance of the system and make it have the advantages of intelligence, the system uses the technologies of the co-modulation, IF digitization, spectrum signal process and self-adaptive antijamming, And the system can choose a optimal modulation type automatically on ballistic trajectory to obtain the best antijamming performance which depends on the situation of battlefield environment/jamming. Introduces configuration, key technologies and realization of the system, and out its performance characteristics and application prospects.
