协同作战系统模数转换最佳量化门限确定方法

协同作战系统中的最佳量化门限研究是指采样有效位一定的情况下,使信号在量化过程中尽可能减小误差,以获得更精确的数字信号处理结果。文中以精确目标定位的协同作战系统为例,建立实际目标传输给不同传感器的信号模型。以保证每个量化值均有同等的概率,与未知模拟信号相匹配作为最佳量化准则,传感器对接收的信号进行量化处理,经过逐层推导,得到用于计算最佳量化门限值的匹配概率公式。

Determination of Cooperative Engagement Capability ADC Quantization Thresholds

The study of optimal quantization threshold aims to reduce the error caused by the procedure of quantization and to get more accurate results of digital signal process when the valid sampling bit number is fixed in the system of synergy fight. This paper takes the system of synergy fight used to detect the target location as an example to build up the actual signal transformed from the target to the different sensors. Making sure that every quantization data has the same probability to match for the unknown analog signal is the optimal quantization norm. Sensors process the signal by the quantization method, and the probability formula for calculating the quantization thresholds is obtained by formula deduction.
