Abstract :
An adaptive-gain α-β tracker combined with circular prediction for manoeuvring target tracking is proposed as a nonlinear prediction filter. For track-while-scan systems using phased array antennas, the reduction of the prediction error is a very important issue. The purpose of this scheme is to achieve good noise reduction and get a better manoeuver-following capability. Simulation results for several target profiles are included for a comparison of the performances of our proposed scheme with that of conventional tracking filters
