Radar Signal Sorting is always a problem of radar countermeasure. In this paper, shifting grids technique is applied to signal sorting. The current grid clustering algorithm, used for radar signal sorting, has some problems such as data input reliance and low clustering precision. So a new signal sorting algorithm based on shifting grids technique is proposed. The algorithm can discover arbitrary...
Precession is significant for midcourse discrimination. By modelling micro-Doppler of spatial precession cone and analysing its modulation characteristic, an instantaneous frequency estimation method based on an effective quadratic time-frequency analysis technique named S-method combined with the inverse Radon transform is proposed to extract micro-Doppler feature. Simulation results with electromagnetic...
The basic theory of polarization application in radar reconnaissance is studied. Under circle polarization-base, the description form of average and instantaneous polarization parameter of radar signals based on Stokes vector estimate is deduced. The models of polarization analysis and average polarization parameter extraction are set up. A local statistical analyzing method of the polarization parameters...
