The invention relates to the field of radio engineering, in particular to the means of simulating radio onboard radar, and can be used for operator training funds jamming and electronic intelligence (RTR). The technical result is to increase the types of generated signals. Radar signal simulator comprising series-connected adder, an amplifier and an antenna, and n, where identical channels forming signals, each of the channels consists of serially connected microwave generator, an electrically controllable attenuator and switch output switch n-th channel signal-connected to a respective input of the adder, and a controller having 2N + 1 outputs, the first output of the controller is connected to combined inputs of microwave generators, n + 1st controller output is connected to a second input electrically controllable attenuator n-th channel signal generating, and n + (N + 2) -th output is connected to the controller a second input switch n-th channel signal generation. Simulator airborne radar signals allows to form n, where
