Detecting and Separating Different Moving Styles Targets of the Over-the-Horizon Radar

The problem of detecting and separating different moving styles targets of the over-the-horizon radar (OTHR) is studied. The echo of the moving target is educed, and a scheme for detecting and separating targets is proposed. The scheme, without any prior information of the targets, combines the Radon-Fourier transform (RFT) with the high-order ambiguity function (HAF), compensates the range-cell crossing and Doppler-cell crossing. Simulation results proved that the scheme is a valid approach to detect and separate different moving styles targets.
