A device that simulates reflected radio waves when radio waves transmitted from a phased array radar to a target are reflected from the target.
In order to give the pseudo target radio waves a motion according to the beam scanning angle of the radar and the beam width of the phased array radar, external equipment sends speed information signals, distance information signals, beam scanning angle signals, and standards as pseudo target information. a Doppler generator that receives the speed information signal and the beam width signal and generates a Doppler signal as a pseudo target signal in response to the speed information signal;
a mixer section that receives the reference signal and connects to the output end of the Doppler generator; a delay circuit section that receives the distance information signal and determines the delay time of the pseudo target signal; and a delay circuit section that receives the beam width signal and responds to the beam width. a first control section that is connected to the output end of the calculation section and controls the output level of the pseudo target radio wave; a first calculation section that determines the output level of the pseudo target radio wave according to the scanning angle; a second calculation section that receives the beam width signal and determines the output level of the pseudo target signal according to the beam width; a first control section that is connected to an output end of the first calculation section and an output end of the second calculation section and controls the output level of the pseudo target radio wave; an output end of the pulse modulation section and the first control section; a variable attenuator that is connected to the output end of the pulse modulation section and the output end of the first control section and changes the output level of the pseudo target radio wave according to the beam scanning angle and the beam width; and the variable beam attenuation section. a first fixed attenuation section connected to the output end of the beam scanning section and giving an attenuation amount corresponding to the beam scanning section to the output pseudo target signal which is the output signal from the variable attenuation section; a second control section that supplies the output signal from the first fixed damping section to the position of the pseudo target determined by the second control section; A phased antenna comprising an antenna section that transmits the output signal from the fixed attenuation section from patch antennas arranged in a plane corresponding to the position of the pseudo target determined by the second control section, and uses this as a pseudo target radio wave. In the array radar test equipment, a second fixed attenuation part is installed between the first fixed attenuation part and the antenna part to correct the difference in the amount of attenuation of radio waves due to the difference in the distance from each patch antenna to the phased array radar. A phased array radar test device characterized by the provision of an attenuation section.
