Abstract
In traditional tracking radars
the joint parameter estimator that is constructed as the Doppler filter bank is optimum in the sense of maximum likelihood
whereas such estimator bears the shortcomings of the considerable complexity in implementation and the loss of detectability in dense target environment.Based on the designing of sub-optimum nonlinear frequency modulated signal
a novel structure that has only two NLFM channels is described
with the performance analysis and the simulation results also presented.
