Problems solved by technology

[0003] However, the currently popular short-distance microwave imaging technology requires first to obtain an echo data set composed of echo data at all equivalent antenna collection positions, and then transmit the echo data set to the signal processing equipment of the security inspection system for further processing. Unified imaging processing can only obtain the image of the target point object, and imaging processing cannot be performed simultaneously during the data collection process, and the data processing efficiency is low

Abstract

The present invention provides a close distance microwave imaging method and system. The rotation of a linear array antenna formed by the preset number of antennas around a preset arc track is controlled to scan a target area, the linear array antenna is controlled to collect the preset number of echo data at the position point of each azimuth on the arc track, and the echo data formed by the preset number of the echo data is sent to a signal processing device until the preset azimuth position point of the linear array antenna on the arc track completes the collection of the echo data; and once the signal processing device receives the echo data set, the echo data set is subjected to image processing so as to effectively improve the processing speed of the close distance microwave imaging, shorten the processing time and realize the real-time imaging.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of short-range microwave imaging, and in particular relate to a short-range microwave imaging method and system. Background technique [0002] Short-distance microwave imaging technology uses the method of actively emitting electromagnetic waves in the microwave band to scan and image objects. Non-ionizing radiation and other characteristics are widely used in security inspection systems to perform human security inspection tasks. [0003] However, the currently popular short-distance microwave imaging technology requires first to obtain an echo data set composed of echo data at all equivalent antenna collection positions, and then transmit the echo data set to the signal processing equipment of the security inspection system for further processing. The image of the target point object can only be obtained by unified imaging processing, and the imaging processing cannot be performed si...
