Abstract:
This thesis presents improving radar target identification by using antenna calibration technique. The antenna calibration technique can improve two main parts of a radar target identification systems. First, the use of the antenna calibration technique can increase the range resolution of the system. Namely, when the antenna effect leading to pulse distortion can be mitigated, the ability of detecting two targets from relatively close range will be improved. Second, the antenna calibration technique will improve the resolution of target identification.
In this thesis, the short-time matrix pencil method (STMPM) is applied to extract poles which is used to identify a target. The poles extracted by using STMPM without the antenna calibration degrades the identification accuracy. This is due to the antenna effect. The use of the antenna calibration technique in radar target identification systems can resolve the underlying problem. Simulations were conducted to validate the proposed method. The simulation results have been shown that the radar target identification system with the antenna calibration technique will be distinctly improved.
