Abstract

PURPOSE:To obtain the echoes faithfully simulated to actual echo signals by so forming the generator that the luminance of the simulation echoes displayed on a radar scope and the angles displayed are changed according to the reflecting area and distance of the flying object to be simulated. CONSTITUTION:In a video generator which supplies simulative echo signals for the radar system, a main memory 1 which stores the azimuth theta, distance R and reflecting area data as the position information from an imaginary flying object and an absolute value subtraction circuit 2 which detects that the absolute value in the difference between the imaginary flying object and the azimuth of the radar antenna is within the correction beam width having been corrected depending upon the distance R and reflecting area of the imaginary flying object, are provided and further a distance memory 7 which writes the echo information and reflecting area information with the distance as address W when the detection signal of said circuit 2 exists and reads the numerical values proportional to the trigger of the system from a distance counter 5 and a 1/R<4> slope generator 10 which generates the amplitudes of the voltage inversly proportional to the power 1000 of the distances and an attached control circuit are provided.
