A METHOD FOR MITIGATING RAIN CLUTTER INTERFERENCE IN MILLIMETER-WAVE RADAR DETECTION

摘要

Method for object detection in rain environment with W-band radar detection system. Radar data of region of interest is obtained, and range-velocity map generated. Initial threshold values are calculated in the range-velocity map. A rain condition is established in the region of interest based on amount of cells in the range velocity map exceeding initial threshold values. If rain condition is present, rain cells and object cells are designated in the range-velocity map, the designated rain cells forming a rain cell pattern. Rain cell threshold values are calculated in rain cell pattern. A first object cluster is detected within the rain cell cluster, a second object cluster is detected outside the rain cell pattern in the vicinity of the first object cluster, and the first object cluster is merged with the second objet cluster to form a unified object pattern. Required information associated with the object of interest is obtained.
