Near-field effect error analysis method

Abstract

The invention relates to a near-field effect error analysis method and belongs to the field of radio frequency simulation. Conventional work such as three-element array antenna near-field effect error analysis in China is all based on analytic methods, which are simple, but cannot achieve accurate results and be applicable in an unlimited frequency range. Therefore the near-field effect error analysis method aims to meet the requirements on high frequency and high precision in radio frequency simulation. According to practical application, the near-field effect error analysis method starts with three array element of a three-element array, develops a computational electromagnetic numerical method, combines electromagnetic simulation software to simulate the near-field effect of a three-element array antenna simultaneously, an azimuth-angle and pitch-angle near-field effect error correction table, and obtains a correct target recurrence position through near-field effect error correction. The near-field effect error analysis method is simple and easy and meets the requirements on high frequency and high precision in radio frequency simulation.

Description

technical field [0001] The invention relates to a radio frequency guidance simulation system, and mainly relates to a simulation target position error analysis method caused by near-field effect errors of three array elements. Background technique [0002] Array radio frequency target simulation has the advantage of being convenient for simulating complex targets and environments, and it is a simulation method that has been adopted both at home and abroad. The application of this technology abroad has been relatively mature. The U.S. Army Advanced Simulation Center (ASC) has successively built hardware-in-the-loop simulation systems for microwave bands and two millimeter wave bands. my country has also built various radio frequency simulation centers, but there is still a gap between them and the United States, Russia and other countries in general. Through years of research in China, the working principle, basic design requirements and methods of this type of system have b...
