The processing method of the parameters of the beam pattern of phased array antennas

The investigation results of the radiation pattern as one of the important parameters of the phased array antenna are presented at the article. Practical results: obtaining skills in using MathCad and researching methods for improving the directional pattern in order to increase the accuracy of determining the goal. The paper presents an algorithm for calculating the radiation pattern of antenna arrays with four modules and a method for improving it. Software and mathematical results are available in the Internet for free, that allows anyone to do similar work to confirm the calculations and conclusions. The results could be used at students practice in technical universities while studying in specialties related to radio electronic engineering in courses connected with study of the design principles of antenna systems with an equidistant arrangement of elements. Publication could be recommended as methodical manual to students for homework solving or laboratory work using specialized MathCad software.
