The Study, Based On Armored Fighting Vehicles, Radar Anti-missile Detection System

With the change of world war situation, the area conflict and counter-strike have been the topic of modern war. The armor vehicle called "the ground god" is becoming the protagonist of war again. But with the development of modern gun-powder and missile technology, the power of all kinds of counter-armor is getting stronger and stronger. This brings austerity verification to the tradition-passive-defense.Active defense system is expounded recently as a new conception, which is aiming for tradition-passive-defense. It includes three module: exploration module, mid-frequency module, determination-command module. This design is based on continuous-wave radar and pseudo-random code concoction .It is an active-defense-system which aiming at counter-armor missile. The system principle is using relevance technology on pseudo-random code and Doppler radar to measure the distance and speed parameter of the coming object, then the embedded device which deal-with data calculates and auto-controls the rocket to protect the coming object. The design of all system includes five parts: catapult, recipient, antenna, min-frequency transact, signal control and process. This paper recites the background and source of this subject and the relevance circumstance in home and abroad, describes the total design project, work principle and course of the system, and accomplish the design of hardware and software of mid-frequency signal transact and signal control and process. The paper assays the data of experiment and gives the conclusion and prospect at last. The success in research on this subject has very important sense to protection of armor, and amplifies the survival ability in battlefield of the armor.
