摘要

月壤水冰预判传感器是利用反射差分光谱法快速判定月壤是否含有水冰的仪器。为了实时获取月壤反射信号和去除混杂噪声，基于现场可编程门阵列(FPGA)，设计了一种月壤水冰预判传感器信号采集和噪声处理软件。通过对采集信号的噪声类型和特点进行分析，提出了累加平均去噪和滑动平均滤波（MAF）相结合的两级实时去噪方案。实验结果表明：该信号采集和噪声处理软件可以实现对月壤反射信号的稳定采集，能够有效抑制耦合噪声和随机噪声，为月壤水冰快速预判提供了更准确的数据。

Abstract

The lunar soil water ice prediction sensor is an instrument that rapidly determines whether lunar soil contains water ice using reflectance difference spectroscopy.In order to acquire the reflection signals of lunar soil and remove mixed noise in real time

a signal acquisition and noise processing software for lunar soil water ice prediction sensor is designed based on field programmable gate array(FPGA).By analyzing the noise types and characteristics of the acquired signals

a two-stage real-time denoising scheme combining cumulative averaging denoising and moving average filter(MAF)is proposed.The experimental results show that the signal acquisition and noise processing software realizes stable acquisition of lunar soil reflection signals

effectively suppresses coupled noise and random noise

and provides more accurate data for rapid prediction of lunar soil water ice.
