With the emergence of the anti-ship missle with the capability of infrared imaging guidance, the traditional single jamming measures, because of the jamming mechanism and technical flaws or unsuitable use, greatly reduced the survival probability of the war-ship in the future naval battle. Intergrated jamming of IR weakening + smoke-screen Can not only make jamming to the search and tracking of IR imaging guidance system , but also has feasibility in conjunction, besides , which also make the best jamming effect. The research conclusion has important realistic meaning for raising the antimissile ability of surface ships.<p> </p>With the development of guidance technology, infrared guidance system has expanded by ir
point-source homing guidance to infrared imaging guidance, Infrared imaging guidance has made
breakthrough progress, Infrared imaging guidance system can use two-dimensional infrared image
information of the target, achieve the precise tracking. Which has Higher guidance precision,
better concealment, stronger anti-interference ability and could Target the key parts. The
traditional single infrared smoke screen jamming or infrared decoy flare interference cannot be
imposed effective interference. So, Research how to effectively fight against infrared imaging
guided weapons threat measures and means, improving the surface ship antimissile ability is an
urgent need to solve.
The future naval battle will take place in a complex electromagnetic environment. Therefore, seizing the electromagnetic superiority has become the major actions of the navy. Radar reconnaissance equipment is an important part of the system to obtain and master battlefield electromagnetic radiation source information. Azimuth measurement function is one of the main function radar reconnaissance equipments. Whether the accuracy of direction finding meets the requirements, determines the vessels successful or not active jamming, passive jamming, guided missile attack and other combat missions, having a direct bearing on the vessels combat capabilities . How to test the performance of radar reconnaissance equipment, while affecting the task as little as possible is a problem. This paper, based on radar signal simulator and GPS positioning equipment, researches and experiments on one new method, which povides the azimuth benchmark required by the direction-finding precision test anytime anywhere, for the ships at jetty to test radar reconnaissance equipment performance in direction-finding. It provides a powerful means for the naval radar reconnaissance equipments daily maintenance and repair work<sup></sup>.
This text makes use of the similar of the principle between IR imaging guided missile detection system and the general sight optics probe. In this text, the synopsis analysis on the jamming effectiveness of the IR smoke projectile resist the IR imaging guided missile is discussed. This research of the jamming technique to IR imaging guided missile have a very realistic meaning.
