Abstract: For the studied the over-determined blind source separation algorithm and its application in radar signal sorting. The reason that natural gradient algorithm of over-determined BSS can not stably converge eventually is analyzed. Aimed at the problem that the exiting methods are analyzed and researched. On-line BSS algorithm with adaptive step length based on separating matrix is presented to implement the optimum combination between the convergence speed and the steady-state error. At the same time, the algorithm can achieve a better separating result when the signal is randomly reduced or increased. The simulation result verifies the convergence stability and the separating effectivity of the two improved algorithms.

Abstract: From the demand of electro-optical countermeasure resources scheduling, a new scheme is provided to effectively solve the reasonable scheduling of resources in this paper. The framework of the collaborative scheduling system of electro-optical countermeasure resources is constructed based on Multi-Agent system. The resources scheduling is simplified through establishing the correspondence of tasks, roles and Agents. Integration methods of a variety of electro-optical countermeasure information are also discussed to provide technical support for electro-optical countermeasure resources collaborative scheduling.
