Research On Radar Signal Sorting Algorithm And Collaborative Jamming Technique

With the development of radar technology, various types of radar have come into being,the detection ability of radar has been improved,which greatly reduces the success rate of missile penetration hold device. In order to improve the success rate of missile prominent enhancement, radar jammer is required. Because of the fact that the operational platform is restricted by space, carrying capacity and energy supply, radar jammer has to be able to detect the enemy radar, as well as jam the enemy radar. Single jammer on enemy radar interference often faces the problem of insufficient resources, therefore, in order to deal with the enemy radar interference, a number of jammers are needed to work together as a system, which is called collaborative jamming system.This paper is devoted to the research on two parts of collaborative jamming system:signal sorting part and collaborative jamming part. It shows the design process of the collaborative jamming system made up of three interference units: hardware design of a jammer signal processing circuit,design of jammer signal sorting program and design of collaborative interference program.The first part of this paper is about the development status of radar jammer. Researches show that the efficiency and jamming effect of radar jammers are not satisfactory due to the constraints of space, carrying capacity and energy supply. Aiming at solving these problems,a unified collaborative jamming system is designed, including the main structure and hardwire units of the system. A twice clustering sorting algorithm modified from K—Means algorithm based on bandwidth and frequency for this unified collaborative jamming system is presented. Then a suited collaborative interfering algorithm is designed based on twice clustering sorting algorithm. Then, verification of twice clustering sorting algorithm and collaborative interfering algorithm are accomplished by doing simulations on MATLAB and CCS5.2. Last, the control program which drives the whole unified collaborative jamming system is designed, the control program is embedded by sorting program and collaborative jamming program. The feasibility of twice clustering sorting algorithm and collaborative interfering algorithm are verified on system hardwire platform.
