【Abstract】 The elastic net is applied to solve the problem of mult i-target multi-sensor passive recognizing and tracking. At first the assemblag e features of the target are described, based on sensors fusion technique on con dition that the sensors detect only bearing angles. And then an elastic net mode l with unfully connected ring architecture is presented by using an expectation template and its dynamics for locking targets is analyzed. The elastic learn rat e and the role of the neurons expectation value and the noise coefficient in red ucing the net noise sensitivity are discussed. At last the simulational results show that WTA mechanism in the receptive field may reduce the computational cap acity a nd the neurons may escape poor local minimums through its adaptive receptive fie ld.更多还原
