For range finders having noncooperative targets and considerable measurement errors, a stochastic analysis is necessary to determine the differentials such as the gradient of a terrain during navigation of navigation of an autonomous platform. The angular measurement errors in elevation or azimuth contribute a deteriorated effect of the gradient estimate, especially when the terror in target is far away. The smoothing of these gradients can be obtained by using an optimization method for approximation involving spline functions. This method can be applied to solve the following problem whether the platform can climb on the estimated in-path slope or whether it will tip over on the estimated crosspath.
