A signal simulator for on-Board altimeters allows carrying out laboratory tests and adjustments, checking functioning in close to real conditions. The reflected signal may be obtained as sum or as combination lot of backscattering signals, corresponding to the reflection from many underlying surface bright points. Semi simulation platform, that can generate a real-time mode signal taking into account vehicle motion dynamics, even at variable modulation parameters, is discussed.
