摘要
针对天波超视距雷达复杂电离层污染校正针对性不强、准确性不高的问题,提出一种知识辅助电离层污染综合校正方案.该方案利用电离层污染知识库、环境监视信息、地/海图库和合作目标库等辅助知识对回波信号所受电离层污染类别进行模式分析与判断,利用多种辅助知识和校正算法库提高复杂电离层污染校正精度,给出了同时存在电离层相位污染和幅度污染时的方案实施步骤.仿真结果验证了该方案的有效性.
In order to solve the problem of weak pertinence and poor veracity of ionospheric contamination correction for skywave over-the-horizon radar(OTHR), this paper proposes a knowledge-aided ionospheric contamination correction scheme, in which the auxiliary knowledge such as ionospheric contamination knowledge base, environmental monitoring information, map/chart library and cooperative target database is used to analyze and discriminate the ionospheric contamination mode of the echo signal. Various auxiliary knowledge and calibration algorithm base are utilized to improve the accuracy of complex ionospheric contamination correction. The paper also presents the scheme implementation steps for the simultaneous presence of ionospheric phase contamination and amplitude contamination. The simulation analysis result verifies the effectiveness of the proposed scheme.
