Double-conical scanning infrared earth sensor earth wave signal processing system

The invention discloses a double-conical scanning infrared earth sensor earth wave signal processing system comprising an earth wave signal preprocessing system and a local terminal unit. The local terminal unit comprises a singlechip, four counters, two timers, and five RS triggers; and the singlechip is used for initialize settings of the counters and the timers. Hardware resources occupied by the double-conical scanning infrared earth sensor earth wave signal processing system are relatively simple; a circuit with the singlechip as a core is capable of realizing dual-channel data processing and uploading; no high-speed device with high value, or analog-digital conversion are needed; data size is relatively small; software processing method is relatively simple; system power consumption is relatively low; reliability is high; and the double-conical scanning infrared earth sensor earth wave signal processing system is suitable for satellite application.
