针对进场雷达在引导无人机自动着陆过程中存在引导数据跳点问题，以及无人机在着陆过程中对引导数据实时性要求，根据进场雷达测量数据连续变化的特点，采用一种新的加权最小二乘数据拟合方法对跳点进行处理，即在数据拟合的基础上估算下一时刻的数据值，并根据下一时刻的测量值和估算值相对预设值的偏差程度，分别对测量值和估算值进行加权，得出可以用于引导无人机着陆的实际值。经算例和仿真验证，表明该方法能够有效降低跳点数据对无人机着陆过程的影响，并具有较好的实时性。

To the problem of the approach radar in guiding the unmanned aircraft(UAV)automatic landing processing about the guidance data hops Issues and the real-time data requirements in UAV automatic landing processing,by using a new weighted least square fitting method to deal with hops.It is based on the characteristics of approach radar measurement data continuously changing.That method is based on data fitting to estimate the data of the next moment value,and according to the measured values and the next moment to estimate the relative degree of deviation preset value,measured and estimated values of weighting respectively.Then the conclusion can be used to guide the UAV automatic landing.
