Matrix Simulator of Echo Signals of Three Antenna Radar Systems

The article discusses matrix simulators used to simulate echo signals of three-antenna radar systems. The problem is that the issues of using matrix simulators for multiantenna systems are poorly understood. It is necessary to use such configurations that would provide adequate simulation simultaneously for all reception channels of the multi-antenna radar. This work presents a development of the results obtained for two-antenna systems. Obtained ratios allow calculating the coordinates of the emitters of a two-dimensional matrix to simulate targets both in azimuth and in elevation. It is shown that the matrix emitters lie in the same plane at the rectangle corners. The resulting array provides a target simulation at the same position for all receiving antennas. As an example, a matrix of four emitters was synthesized. The matrix has been tested using numerical modeling. The results of the numerical experiment confirmed the reliability of the obtained theoretical ratios.
