Angle Estimation Method using Blocking Matrix in Stepped Multiple Frequency Complementary Phase Code Modulation

摘要

In this paper, we consider the angle estimation method using monopulse angle estimation in the situation where the targets has same velocity and are located on very close range which is comparable to the range resolution. For these situations, we consider the angle estimation method using combination of Super-Resolution (SR) and Blocking Matrix (BM). From the simulation results, the bias error of the proposed method is less than 0.5 deg from the true value, when the input S/N is enough high. It also shows a tendency that the random error of proposed method is lower than that of conventional method and the error reduced with the increasing S/N ratio. From the initial experimental result, the proposed method can obtain the target angle by monopulse angle estimation for the targets which have same velocity and are located on very close range, which is equivalent to the half of range resolution.
