A variety of signals simulators can be use for laboratory testing radar systems (radar) instrumentation. The proposed simulator allows function verification of full system, including antennas, receivers and transmitters, in condition of variable parameters of channel distribution of radar signal. The reflected signal can be obtained as a sum or as combination lots of backscattering signals corresponding to the reflection from the many underlying surface or radar target bright points. Examples and experimental results of seminatural modeling with a serial radio altimeters at variable parameters of the reflected signal formation are given.
