・アレー・レーダー試験装置。 A device that simulates a reflected signal when radio waves transmitted from a phased array radar to a target are reflected from the target, simulates the movement of the simulated target according to its speed and distance. A Doppler generator receives a speed information signal, a distance information signal, and a reference signal as pseudo target information from an external device in order to give the target signal, and receives the speed information signal and generates a Doppler signal of the pseudo target signal. a mixer section that receives the reference signal and connects to the output end of the Doppler generating section; a delay circuit section that receives the distance information signal and determines the delay time of the pseudo target signal; and an output end of the mixer section and the delay circuit section that receives the distance information signal and determines the delay time of the pseudo target signal. In a phased array radar test equipment consisting of a pulse modulation section connected to the output end of the circuit section and performing pulse modulation, it receives a beam scanning angle signal from an external device and outputs a pseudo target signal according to the beam scanning angle. Added a calculation section that determines the level, a control section connected to the output end of the calculation section, and a variable attenuation section connected to the output end of the control section and the output end of the pulse modulation section that changes the output level of the pseudo target signal. A phased array radar test device that is characterized by:
