Background

The lightning imager is one of main payloads of FY-4A satellites (Fengyun No. A satellite), and has the main function of realizing real-time and continuous detection of lightning in a geostationary orbit and acquiring a lightning distribution map within a detection coverage area. The lightning detection method comprises the steps that a satellite detects lightning, relatively weak lightning signals are required to be extracted from a strong background, a lightning imager carries out frame-by-frame background estimation and background dimming on the satellite on the basis of adopting various filtering technologies, the process can inhibit background noise interference, and lightning data are only downloaded to the ground. The on-board background suppression process is one of the core steps of on-board lightning detection, and the accuracy of which is directly related to the detection capability of a lightning imager. Therefore, the FY-4A lightning imager is provided with a lightning detection original pixel data downloading function, the lightning event data are 400 (north and south) ×600 (east and west) pixel comprehensive array detection data, the lightning original pixel data are 1/80 of the comprehensive array detection data, the corresponding area size is 100 (north and south) ×30 (west) pixels, and the area selection of the lightning original pixel data can be realized through a lightning detection original pixel area switching instruction.

Lightning imager has three modes of operation: a lightning detection mode, a landmark detection mode and a program uploading mode, wherein the default working state is the lightning detection mode. And in the lightning detection mode, the lightning comprehensive array data and the area lightning original pixel data of the 1/80 comprehensive array are respectively downloaded. By utilizing the original pixel area switching function of lightning detection, the original detection of a lightning imager in a designated area and a designated time period can be analyzed, and then an on-orbit on-board background suppression processing algorithm is adjusted. In actual operation of the lightning imager, the lightning threshold algorithm, the double-sided lens lightning detection capability, the FPGA chip lightning data processing capability, the focal plane assembly data processing capability and the lightning detection capability of different areas are found to be different, and the original detection data in the whole field of view of the lightning imager and the lightning detection original data of each switching area in different periods of the day are obtained in a long-term accumulation mode by designing various modes for switching the lightning detection original pixel areas in a round-robin mode so as to support the research of the background radiation characteristics of the lightning imager, provide reference basis for improving the on-board background suppression processing and improve the detection capability of the lightning imager.

The original working state of the lightning imager adopts a fixed area lightning detection original pixel, a manual switching mode is adopted in a changing area, one lightning original pixel area can be changed only by one manual switching, long-term accumulation of the lightning detection original pixel data of the comprehensive array cannot be met, and the lightning detection original pixel data requirements of each switching area in different time periods in one day can not be met.

The present invention has been made in view of this.
