On the Errors Arising from the Use of Discrete Surface Models for Land Clutter Simulation

The paper analyzes influence of a discrete model of reflective features of the earth surface on the error of echo signal simulation. It is shown that the discreteness leads to the errors in calculating a power of the signal simulated. An evaluation of the error level and its dependence to the discretization step is obtained. The requirements to the sampling period determining the adjusted error level are presented.
