差分GPS整周模糊度的的经典解算算法——LAMBDA算法及基线的实时解算(Classic Differential GPS ambiguity of the solver algorithm and real-time solution algorithm LAMBDA baseline count)

说明：  针对高动态 环 境 下 突 发 信 号 检 测 问 题，提 出 基 于 高 阶 项 逐 级 消 去 的 非 线 性 调 频 （ｎｏｎ－ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ ｍｏｄｕｌａｔｉｏｎ，ＮＬＦＭ）信号参数估计算法，利用合理近似，将其转化为相对简单的线性调频 （ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ　ｍｏｄｕ－ ｌａｔｉｏｎ，ＬＦＭ）信号参数估计问题，并提出两级调频率逼近法用于ＬＦＭ 信号参数估计，具有原理简明、计算复杂度低 等特点，便于实际工程应用．(To detect burst signals in high dynamic environment, a non-linear frequency modulation (NLFM) based on high-order item elimination is proposed. Modulation (NLFM) signal parameter estimation algorithm, using reasonable approximation, is transformed into a relatively simple linear frequency modulation- The problem of LFM signal parameter estimation is discussed. A two-stage frequency modulation approximation method is proposed for LFM signal parameter estimation. It has simple principle and low computational complexity.)
