    Abstract
  • Constant False Alarm Rate (CFAR) detection is the main method used in the ship detection of High Frequency Surface Wave Radar (HFSWR). The present Automatic Identification System (AIS) based verification methods of CFAR results is an indirect method,which are subject to the influence of the direction estimation error and lack of the ability of analyzing the situations of false target and miss detection. In this paper,we introduced a direct method to evaluate the CFAR ship detection results of HFSWR based on range-Doppler projection of AIS data. The AIS data were converted and presented on the range-Doppler spectrum of HFSWR. These information were then associated with the CFAR results to facilitate direct evaluation. The principle and procedure of our method were introduced in detail,and the practical applications in CFAR results of field data were provided. It was demonstrated to be an effective verification method. Moreover,it could contribute to the parameter adjustment of CFAR in detection of low observable targets.
