Energy particle detector signal processing system and method

Abstract

The invention relates to an energy particle detector signal processing system and method, and the system comprises: a pre-amplifier module which converts an electric pulse signal outputted by an energy particle detector into a voltage and then converts the voltage into a charge; a analog ASIC chip which is used for processing the charges and outputting a differential current signal; a conditioningcircuit which is used for carrying out current-voltage conversion on the differential current signal output by the analog ASIC chip; an ADC module whch is used for digitalizing the voltage signal output by the conditioning circuit; a trigger signal generation module which is used for processing the electric pulse signal output by the energy particle detector to generate a trigger output signal; acalibration module which is used for carrying out regular on-orbit calibration; a high-voltage field circuit which is used for providing bias high voltage for enabling each energy particle detector to work normally; a DAC module which is used for generating voltage signals with different amplitudes; and a core processing system which realizes noise removal, temperature compensation, state monitoring, high-energy particle type identification and system on-orbit calibration, and performs data communication with the load controller.

Description

technical field [0001] The invention relates to a signal processing system and method of an energy particle detector applied in a deep space environment, and relates to the technical field of space charged particle detection. Background technique [0002] The exploration of terrestrial planets has always been the first choice for human beings to go out of the earth-moon system and carry out deep space exploration. From the 1990s to the present, the development of new technologies and the acquisition of scientific discoveries have been the main driving force in the world, which has given birth to a new upsurge in the exploration of terrestrial planets, and has expanded from the United States and Russia to Japan, Europe, India and other countries. my country also officially approved the project in 2016, which will realize the orbiting, landing and patrolling of terrestrial planets for the first time. [0003] As one of the payloads of the orbiter, the energy particle detector...
