The main function of ESM is to receive, measure, deinterleave pulses and then identify alternative threaten emitters, among which pulse deinterleaving process is significantly difficult and important. Dense electromagnetic environments cause an ESM to receive a seemingly total random pulse stream with large noise. The traditional algorithms have behaved weak and unstable under the rather severe situation,...
Navigation and surveillance applications require tracking constant input/bias targets. When the target's trajectory follows a constant input/bias constraint, model mismatching caused by conventional tracking algorithms can be handled by a delayed update filter (DUF). The statistical convergence and stability properties of the delayed update filter were studied to insure the rationality of its steady-state...
A Kalman filter with delayed update filter (DUF) is proposed for mining the steady-state performance when tracking a constant input/bias target, while its transient performance is maintained when maneuver occurs. The key of this scheme is using a constant input/bias constraint as a pseudo-measurement to update current states estimated via Kalman filter. This constraint can remove the influence caused...
