Multi-targets Detection in DBS via Keystone Transform
Doppler Beam Sharpening (DBS) is a technique which can improve the resolution of radar azimuth. Aimed at the problem of range walk through resolution cell in DBS imaging, a new algorithm which corrects the range walk based on keystone transform is proposed. In this algorithm, a linear transform on the received data is employed to correct different range walk values without requiring the kinetic information and the look angle of the radar platform in the multi-targets environment. This method can realize coherent integration in azimuth dimension and improve the azimuth resolution. A fast implementation of keystone transform is used to satisfy the real-time processing of DBS imaging.Numerical examples are provided to demonstrate the performance of the proposed approach.
