Abstract


Anti-radiation seeker technology is the focus of military research projects , its technical performance of a direct impact on the performance of anti-radiation missile attack . Seeker has a wide operating frequency range , the antenna aperture size is limited by the diameter bomb seeker 's angular resolution . For the multiple emitter signals exist within the main beam is difficult to achieve accurate direction finding and tracking . The paper 's main purpose is to study the anti-radiation seeker angle resolved and angle tracking algorithm for multi-source signal . In this paper , the first anti-radiation seeker the angle resolution method for multi-source signal . Multiple pulses of radiation sources for the seeker, the main beam of the memory in the time domain gating ( or weighing frequency tracking) and cluster analysis method , separation and tracking specific sources of radiation . Simultaneously access seeker within the main beam of the plurality of sources of interference, particularly in terms of the time domain , the frequency domain can not be distinguished noise FM interference , analysis of the receiver the response characteristics of the sources of interference , as well as a plurality of sources of interference when acting simultaneously on the angle measurement the impact . And then , on the basis of research based on the cluster analysis and spatial filtering angle resolution algorithm , this algorithm will be applied to the seeker tracking the course of the two sources of interference . Simulation results show that the proposed method is effective , greatly improved seeker angle-resolved multi-objective . In addition , the practical problems encountered in multi - source signal angle-resolved and angle tracking process , track identification sidelobes , anti- multipath , anti-glare interference analysis and processing method .
