摘要:
针对以往微波成像仪中的多通道采集系统只能顺行采集数据,不能控制通道采集起始时间和采样间隔的问题,提出了多通道并行可程控遥感数据采集系统。该系统在硬件上采用多个通道完全并行采集,通过现场可编程门阵列(FPGA)控制,当接收外界注数指令后,实现遥感采集的起始时间可调和采样时间间隔可变的功能。试验结果表明,该采集系统能够同时控制多路通道并行采集、采样时间可控的功能,并且采样的信号稳定,精度达到毫伏级别。
Abstract:
A solution of multi-channel parallel programmable remote sensing data acquisition system was proposed to solve the problem that the multi-channel acquisition system in the microwave imager could only collect data anterogradely and could not control the channel acquisition start time and sampling interval. The system adopted multiple channels for completely parallel acquisition on the hardware and was controlled by FPGA (Field-Programmable Gate Array). After receiving external number instructions, the system could implement the function of adjusting the start time of the remote sensing acquisition and changing sampling intervals. Test results showed that the acquisition system could simultaneously control the parallel acquisition in multiple channels with controllable sampling time, stable sampling signal and millivolt-level accuracy.
