介绍了雷达成像中的几种插值算法.采用散射点幅度值、图像熵和运行时间作为参数对不同的插值方法进行了比较.用点目标进行仿真,结果表明在雷达成像中三次样条插值是一种比较好的插值方法,可在实际中应用此方法.

This paper introduces several interpolation methods to reconstruct radar imaging. In order to compare different methods some parameters such as amplitude value, image entropy, as well as computational time are used. Simulation of point target model is built. It is demonstrated that the cubic spline interpolation technique is a good method and can be applied in practice.
