Abstract
In this paper, two angle estimation methods for applying the stepped multiple frequency CPC radar are considered. One is 2-D Super Resolution (2-D SR) (Method I) and the other is the combination of 1-D SR and Blocking Matrix method (BM) plus monopulse angle estimation (Method II). From the simulation results, the range and angle are obtained by both methods even in the situation where the targets have same velocity and located on the very close range and angle each other. RMSEs of Method I for both range and angle are smaller than those of Method II. On the other hand, both random and bias errors of Method II are smaller than those of Method I in the experiments. The results indicated that Method II has a tolerance to the calibration errors that exists in the actual measurements.
