Abstract
In this paper, the principle of Unscented transformation is analyzed and an improved UKF (Unscented Kalman Filter) algorithm is proposed based on electronic technology. To simplify the computational complexity of the tracing system, identity matrix is introduced to the Unscented transformation, by which the complicated matrix calculation is replaced by simple numerical calculation for matrix square root solving. The new method called FMSRUKF (Fixed Matrix Square Root Unscented Kalman Filter) is an improved algorithm of UKF on target tracking based on Electronic Technology. Simulation results of variably accelerated motion target tracing under three dimensional coordinate shows that FMSRUKF achieves better precision and robustness.
