Problems solved by technology

Although the existing visible light and infrared instantaneous large-field imaging systems have greatly improved the airspace surveillance range and can meet the needs of all-day surveillance and guidance, they cannot effectively deal with information countermeasures such as infrared stealth and decoys; and microwave bands are difficult to detect due to wavelength constraints. Realize miniaturized instantaneous wide field of view system
[0004] Problems existing in the existing technology: The existing terahertz imaging system must obtain an instantaneous large field of view through mechanical scanning, and the imaging speed is slow and the volume is large

Abstract

The invention discloses a small-volume large-view-field multi-channel terahertz array detection imaging system comprising a terahertz imaging front end, a signal processing module and a main control module. The terahertz imaging front end includes a terahertz lens including a curved microlens group and a folding lens, a terahertz array chip with a detection antenna structure as a basic pixel, anda readout circuit. The target tracking and recognition are realized by using an image stitching algorithm, a detection-and-tracking algorithm, and an abnormal pixel detection and interpolation compensation method and the system robustness is improved. The system is suitable for the military defense application fields like the wide airspace supervision and guidance.

Description

technical field [0001] The invention belongs to the technical field of terahertz imaging, and in particular relates to a small-volume, large-field-of-view multi-channel terahertz array detection and imaging system. Background technique [0002] Instantaneous large field of view imaging technology has important application value for persistent real-time dynamic monitoring of large areas. The instantaneous field of view of traditional imaging systems is usually small. For example, the AIM-9R Sidewinder missile using infrared focal plane array imaging front end has an instantaneous field of view of 25°; the Soil Moisture Active and Passive Satellite (SMAP) using microwave synthetic aperture imaging technology ), its instantaneous field of view is only 4°. It can be seen from this that in order to obtain wide-area images, traditional imaging systems usually need to use scanning methods, that is, time-domain resources need to be exchanged for air-space resources. Therefore, tra...
