Abstract

Abstract:

A novel algorithm for high-speed multi-target detection and parameters estimation with narrowband radar is proposed. Firstly, velocity and acceleration are roughly estimated with the combination of compensating range migration in the frequency domain and fractional Fourier transform. And then, based on the coarse estimation, keystone transform and fractional Fourier transform are employed to estimate the fold factor and acceleration accurately. In the case of multi-target, range migration, Doppler spread and velocity ambiguity, this algorithm is suitable, and the performance of the targets detection and parameters estimation is improved owing to the utilization of the coherent integration in a low signal-to-noise ratio. The computational load is greatly reduced by combination of coarse and accurate estimation. The validity of the proposed algorithm is demonstrated by computer simulation.

Key words: range migration, fractional Fourier transform, Keystone transform, Doppler spread, velocity ambiguity, coherent integration
