A Velocity Vector Estimation Method Based on Radar Extended Target
Fan Jian-pen · Acta Armamentarii · 2013
For the target performing relatively uniform linear motion in the fuze phase,a velocity vector estimation algorithm is proposed based on least square method using the measurements of Doppler velocities and angles of multiple scattering points obtained by the seeker radar. The estimation can be used to predict the explosion point and detonation time,thereby greatly enhancing the fuze performance. Numerical simulations have demonstrated the effectiveness of the proposed approach.
