AI Technical Summary
The existing electronic systems of spaceborne fluorescence hyperspectral detectors have insufficient signal-to-noise ratios under low brightness and weak signal conditions. Furthermore, the electronic systems are numerous, large in size, and consume a lot of power, making it difficult to meet the requirements for high integration and miniaturization.
A highly integrated electronic system for a spaceborne fluorescence hyperspectral detector with a high signal-to-noise ratio was designed, including a signal processing unit, a timing control unit, and a focal plane driving unit. It employs an ultra-low noise analog-to-digital conversion module, a low-noise analog signal active filtering module, and an analog signal preprocessing module. Circuit noise is reduced through various noise suppression methods, and 1553B bus communication function is integrated through an FPGA module to reduce the number of devices.
It significantly reduced system noise, improved the signal-to-noise ratio, reduced the number of devices and resource consumption, compressed the system size and weight, and improved the integration and efficiency of the detector.
