摘要
针对基于动态目标模拟方法,检验和考核高精度测速设备性能,训练操作手的实战水平,提出了一种基于高精度测速设备理论弹道的动态模拟方案,通过对预先提供的理论弹道文件,进行插值、坐标转换和中频模拟等步骤,解算出理论弹道文件中包含的信号电平、多普勒频率和目标位置等信息,并据此产生中频模拟信号[1,2]。模拟信号作为动态模拟信号送给高精度测速设备,用于检验和考核设备性能,训练操作手的实战水平。利用理论弹道数据产生高精度测速设备的动态模拟数据,具有精度高、贴近实战的特点。
For inspection and assessment of high precision measurement device performance and the actual combat training of operator based on dynamic target simulation method,the paper proposes a dynamic simulation scheme of high precision measurement device based on theoretical trajectory. Interpolation,coordinate conversion and IF simulation are performed for the theoretical trajectory files provided in advance,the signal level,Doppler frequency and target position information contained in the theoretical trajectory file are calculated,based on which the IF analog signal is generated. The analog signal is sent to the high precision measurement device as the dynamic simulation signal for inspection and device performance test as well as the actual combat training of operator. Generating the dynamic simulation data of high precision measurement device by using the theoretical trajectory data has the characteristics of high precision and being close to actual combat.
