研究了重频参差相参脉冲串的频率估计算法。通过脉内相关积累,提高了新序列的信噪比。对新序列的相位差按参差重数抽样平均,减小了等效的相位噪声方差,利用重频参差比解相位模糊,扩大了频偏允许范围,降低了算法的信噪比门限。分析了本算法实现相参频率估计的条件,推导了相应信噪比门限的解析表达式,指出了信噪比门限与信号样本总数、参差重数、参差比之阎的关系。仿真结果表明:上述结论是正确的,在满足信噪比门限条件下,频率估计的精度接近相参脉冲串频率估计的克拉美一罗限(CRLB)。(Frequency Estimation for Staggered Coherent Pulse Train)

将Iris数据集分为2组,每组各75个样本,每组中每种花各有25个样本。其中一组作为以上程序的训练样本,另外一组作为检验样本。为了方便训练,将3类花分别编号为1,2,3 。
使用这些数据训练一个4输入(分别对应4个特征),3输出(分别对应该样本属于某一品种的可能性大小)的前向网络。(The Iris data set is divided into two groups each of 75 samples in each group have 25 samples in each flower. One set of sample programs as more training, another group as the test samples. To facilitate training, the three types of flowers were numbered 1,2,3. Training before using these data a 4-input (respectively 4 features), 3 outputs (respectively the possibility should belong to a variety of sample size) to the network.)
