Circuit system of an optical remote sensor

Abstract

A circuit system of an optical remote sensor relates to a space optical remote sensor. It includes system control unit and focal plane circuit components. The system control unit generates a working parameter setting instruction and sends it to the focal plane circuit assembly; the focal plane circuit assembly includes N parallel focal plane circuit units; each focal plane circuit unit includes a focal plane processing circuit and a focal plane TDICCD circuit, and the focal plane processing circuit Receive the working parameter setting instruction issued by the system control unit, and generate a timing signal to output to the focal plane TDICCD circuit; the focal plane TDICCD circuit generates a TDICCD analog image signal and sends it to the focal plane processing circuit; the focal plane processing circuit digitizes the TDICCD analog image signal After processing, it is sent to the external satellite data transmission subsystem. The invention has obvious improvements in volume, weight and power consumption, and can meet the design requirements of existing satellite loads for high-resolution and large-width optical remote sensors.

Description

technical field [0001] The invention relates to a space optical remote sensor, in particular to a circuit system of the optical remote sensor. Background technique [0002] In commercial and civil fields, optical remote sensing images have important application value in land, agriculture, urban planning, etc., and can be used for land and resources survey management, town planning, post-disaster assessment of natural disasters, and provide effective monitoring for post-disaster reconstruction, etc. and investigative tools. At present, it is difficult for domestic user units to purchase high-resolution and large-width optical remote sensing image data from abroad. In order to meet the growing demand for high-spatial and high-time-resolution remote sensing image data in my country's civilian fields, and to meet the needs of monitoring capabilities for specific targets and hotspot areas, the development of high-resolution and large-width optical remote sensor systems has becom...

Problems solved by technology

In order to meet the demand of large width, the number of CCD splicing will increase a lot. If the existing circuit system is adopted, the size, weight and power consumption will be greatly increased. At present, the existing satellite platform load resources are tight, Power resources and space resources are very limited, unable to meet the existing satellite load design requirements
