Use this GUI for fitting 2-port S-parameters using the functions from RF Toolbox

解压之后.添加到matlab->file->set path里面,就可以直接运行InvGUI.输入具体的数值后,自动plot figure.(After decompression. Added to the matlab-> file-> set path inside, you can directly run InvGUI. Enter specific values, the auto-plot figure.)

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)
