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)

This project proves to be a very useful home and office appliance as it eliminates the worry of user to open & close a door. In this project we have not operate door as we did manually as push and pull a door.Project circuit sens a human interference and accordingly it is open & close door. The term automated doors includes full powered automated doors such as those that are commonly used at supermarkets and transportation terminals and low energy and “power assist doors that are used in less demanding situations. Here it doesn’t require conventionally pull and push the door. So it can be useful for Handicap people. It is easy to use and affordable.
