SECURITY CHECK METHOD AND SYSTEM BASED ON MICROWAVE IMAGING OF HUMAN BODIES

摘要

A security check method and system based on microwave imaging of human bodies. The security check method comprises: pre-create at least four parallelly operating threads, one thread being responsible for movement control and data acquisition, one thread being responsible for imaging processing, one thread being responsible for interface displaying, and one thread being responsible for target detection and recognition (S201); then the four concurrently operating threads divide original echo data of a human body to be checked into data of a plurality of adjacent overlapped azimuthal segments during data processing and perform individual processing on the data of each azimuthal segment. The security check system comprises a thread creating unit (1), a first thread parallel unit (2), a second thread parallel unit (3), a third thread parallel unit (4), a fourth thread parallel unit (5), and a thread loop control unit (6). Because subsequent data processing is not required to be performed after the acquisition of all data is completed, the period of time for a security check process is reduced.
