Embodiment Construction

[0041] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0042] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0043] figure 1 The schematic diagram of the front end of the radiometer provided for the embodiment of the present invention is described in detail as follows.

[0044] The front end of the radiometer may include: a metal box body 101, a boss 102, a quartz probe 103,...

Abstract

The invention applies to the technical field of terahertz security check, substance detection, remote sensing and medical diagnosis and provides a radiometer front end and terminal equipment. The radiometer front end comprises a metal box body, wherein a groove is set at an upper side face; a plurality of bosses are set in the groove; a first low noise amplifier chip, a second low noise amplifierchip and a detector chip are set on the corresponding bosses in sequence; a quartz probe is set in the groove of the metal box body and is located at a left side of the boss corresponding to the firstlow noise amplifier chip; a video amplifier is set in the groove of the metal box body and is located at a right side of the boss corresponding to the detector chip; and conductive wires are set between the bosses in the groove of the metal box body, between the quartz probe and the boss corresponding to the first low noise amplifier chip, and between the boss corresponding to the detector chip and the video amplifier; and adjacent devices are electrically connected through utilization of the conductive wires. A size of each circuit can be remarkably reduced.

Description

technical field [0001] The invention belongs to the technical fields of terahertz security inspection, material detection, remote sensing and medical diagnosis, and in particular relates to a radiometer front end and terminal equipment. Background technique [0002] A radiometer is a high-sensitivity receiver used to measure the thermal radiation of objects and is the main tool for passive microwave remote sensing. At present, microwave radiometers based on ground-based (including ground and ship-borne platforms), space-based (including aircraft, missile, balloon platforms), satellite-based (including satellite, spacecraft, space shuttle platforms) and other carrier platforms have been developed rapidly. The radiometer has also developed from the meter-wave radiometer to the current millimeter-wave, sub-millimeter-wave and even terahertz radiometers. Terahertz can pass through non-metallic and non-polar materials with little attenuation, and realize terahertz imaging detect...
