提出时间压缩和分流降频算法以及硬盘阵列存储方法，并由此实现一种新颖的解决了跟踪雷达对跟踪波门内的雷达回波信号的高速大数据量信号实时采集和存储系统。文中介绍了时间压缩和分流降频算法原理，以及高速大容量数据实时采集存储多机处理系统硬件的工作原理和软件设计思想。该分流降频算法采取多硬盘阵列处理方法具有普遍意义，可用于其他类似的系统中。对于搜索雷达等需要对全程回波信号进行这种处理时，也可利用分流降频算法采取多硬盘阵列处理。

This paper presents algorithm on time compression and bypass flow reduce frequency along with method of hard disk array storage. A novel real-time acquisition and storage system have been implemented for high-speed mass data of radar echo signal in track wave gate on the track-while-scan radar. Principle of time conpression and bypass flow reduce frequency along with multi-computer multi-hard-disk asynchronous concurrent storage technique is introduced.
