An improved orthogonal matching pursuit (OMP) algorithm is proposed for the detection of multiple high-speed maneuvering targets. Based on the maneuvering characteristics of a high-speed target, a signal model is established at first. Then, an improved OMP algorithm is used to estimate motion parameters. In addition, a phase compensation function is constructed to correct for the range migration and Doppler migration. Finally, coherent integration can be achieved by the fast Fourier transform (FFT). The suggested technique may successfully avoid the effects of the signal cross term and blind speed side lobe in multi-target high-speed maneuver identification settings.Meanwhile, it has the advantages of high accuracy of parameter estimation and strong anti-noise robustness. The suggested algorithm’s efficacy and dependability are confirmed by the simulation results.
