In the simulation the radar signal also can be replaced by any defined signal through data file reader in which the recorded or other custom data can be easily used. Normally, if you sum a number of equally-weak or strong random influences you get something that is Gaussian, but remember in this context you are talking about POWER, and you are really talking about the magnitude squared of a complex number (radar data being assumed to be complex-valued baseband samples). Although most designs will leave some margin above the required power, it is unlikely that an existing system can accommodate eight times more power; (2) it is very expensive to replace the hardware to. Basically an elementary radar system consists a transmitter and receiver, each connected to a directional antenna. pulse-to-pulse.
