基于Flash的侵彻关键信号分区存储方法

Penetration Signal Storing Based on Flash Partition Storage

针对弹体侵彻硬目标过程中,关键信号获取存储难度大,有效数据易丢失、被覆盖的问题,提出了基于Flash的侵彻关键信号分区存储方法。该方法将Flash存储单元逻辑上分为两区,通过判断弹体是否侵彻目标掉电,从而跳区将侵彻关键有效数据捕获并锁存至单次记录的第二区。实验表明,该分区存储方法获取关键信号准确可靠,记录数据完整度高,具有很好的应用价值。

In the process of hard targets penetration,the key signal is hard to be captured and stored,the valid data is li-able to be lost and covered.A key penetration signal partition storage method based on Flash was proposed in this pa-per.This method logically divided the flash memory into two areas.It would jump to the second area to capture and storage key penetration valid data by single record if missile penetration target power was down.Tests showed that this partition storage method was accurate and reliable on capturing key signal with high recording data integrity.
