In the background of signal detection for high frequency (HF) radar, the sea clutter is quite significant and can mask some weak target signals. A new clutter rejection method named "nonlinear projection" is given to improve the SNR of the target. This approach is based on the recent o...

In an active radar-tracking system, the target-motion model is usually modeled in the Cartesian coordinates, while the radar measurement usually is obtained in polar/spherical coordinates. Therefore the target-tracking problem in the Cartesian coordinates becomes a nonlinear state estimation problem...

A new method on radar signal polarization filtering using only single sample of signal is proposed. The algorithm is very simple and it is suitable for the filtering processing of a stationary or unstationary polarization signal. Some simulation results on radio disturbance suppression are given.
