DETECTION DEVICE, RADAR DEVICE, DETECTION METHOD, AND DETECTION PROGRAM

摘要

[Problem] To obtain a detection image in which a large target is not suppressed. [Solution] a Doppler processing unit (20) is provided with a sweep buffer (21), a Doppler filter bank (22), log detection units (23A-23N), CFAR processing units (24A-24N), a combination unit (25), a large target identification unit (26), and a combination unit (27). The Doppler filter bank (22) generates a plurality of Doppler frequency components from a plurality of pieces of sweep data from the sweep buffer (21). The CFAR processing units (24A-24N) perform CFAR processing using a plurality of post-log detection Doppler frequency components. The combination unit (25) combines the post-CFAR processing Doppler frequency components and generates post-CFAR processing sweep data. The large target identification unit (26) detects a large target from the data value of the sweep data and generates complementary sweep data in which the data value is corrected in accordance with the detection result. The combination unit (27) combines (performs MAX extraction processing of) the post-CFAR processing sweep data and the complementary sweep data and outputs the result.
