摘　　要：干涉仪测向定位是一种被广泛应用的空间无源定位技术。由于电磁空间环境脉冲密度较大,通过脉冲分选、相位差校正及相位解模糊等处理流程得到辐射源参数和位置信息,时延较大。针对该问题,提出了一种基于多线程并行的干涉仪测向定位快速处理方法。通过QRunnable类定义干涉仪测向定位的多线程算法,将单个节拍数据的串行处理流程,利用多线程并行计算的方式实现高效计算。通过仿真测试,验证了快速处理方法的有效性,该方法具有较好的工程应用价值。Interferometer direction position is a widely used spatial passive positioning technology.Due to the high pulse density of the electromagnetic space environment,the radiation source parameters and position information are obtained through the processing processes of pulse sorting,phase difference correction and phase solution blur,which is poor in timeliness.To solve this problem,a fast processing method of direction finding and position with phase interferometers based on multi-thread parallel has been proposed.This method changes the serial processing of single beat data to multi-thread parallel computation through the function of QRunnable class.Through simulation tests,the effectiveness of this method is verified,which has good engineering application value.
