| Abstract(in English) | In the multi-static radar, the sum of the distance between the transmitting antenna and the target and the distance between the receiving antenna and the target can be observed. Similarly, the Doppler Sum can also be observed. From these range sum and Doppler sum, the three-dimensional target position and velocity can be estimated by using the Taylor series estimation method that is also used in the TOA method and the like. In the Taylor series estimation method, an initial value (target position, speed) for estimation is provisionally set, and target position and velocity are estimated. Then, the estimation result is used to renew the initial value. This process is iterated until the convergence value is obtained. In this paper, the number of times required for convergence is evaluated by simulation in the case of 4 receiving antennas assuming vehicle surveillance at the intersection. As a result, it was found that if the initial value does not differ greatly from the true value, the position and velocity converge in several times. In addition, even if the initial value is different from the true value, the position estimation performance is better when using additional Doppler sum rather than only range rum. |
