基于蒙特卡洛方法的主动声纳信号检测性能分析.主动声纳信号检测性能的分析上,目前在计算机仿真中一般假定混响包络的统计特性符合瑞利分布模型。基于此模型,已经有了较完善的理论。然而,在现代高分辨声纳系统中,混响包络的统计特性并不符合瑞利分布模型。此时在接收机工作特性分析时存在大量繁琐的公式推导。因此该文采用蒙特卡洛(M onte Carlo)统计试验方法,实现对瑞利分布混响背景下的主动声纳信号检测性能分析。结合对接收机工作特性曲线的仿真,得出了检测概率的理论值和仿真结果的误差曲线。误差曲线表明,蒙特卡洛方法在主动声纳信号检测的性能评估中是可行的。 更多还原
(Active sonar signal detection performance analysis, computer simulation is generally assumed that the statistical properties of the reverberation envelope distribution model of Rayleigh active sonar signal detection performance analysis based on the Monte Carlo method. Based on this model, has been a better theory. However, in the modern high-resolution sonar system, the statistical characteristics of the reverberation envelope does not comply with the Rayleigh distribution model. At this point in the receiver operating characteristic analysis, there is a lot of tedious formula derivation. In this paper, using the Monte Carlo (M onte Carlo) statistical test methods, active sonar signal detection performance analysis reverberation background Rayleigh distribution. The receiver operating characteristic curve simulation obtained the error curve of the theoretical value and the simulation results of the detection probability. The error curve shows that the Monte Carlo method in the assessm)

STM32F103C8T6通过MAX31865读取PT100电阻值
http://blog.csdn.net/gsh_hello_world/article/details/52900276
STM32F103C8T6通过MAX31865读取PT100电阻值，使用TB1621驱动LCD进行显示。图中的两个红线中的任意一个和蓝线之间即为PT100电阻，二线制时只需要将两根红线中的一根和蓝线接入到电路即可，三线制时需要将三根线都接入电路。。MAX31865是简单易用的热敏电阻至数字输出转换器，优化用于铂电阻温度检测器(RTD)。外部电阻设置RTD灵敏度，高精度Δ- Σ ADC将RTD电阻与基准电阻之比转换为数字输出。MAX31865输入具有高达±45V的过压保护，提供可配置的RTD及电缆开路、短路条件检测。
