Abstract

The invention discloses a rectangular coordinate system-oriented antenna radiation pattern setting method for a signal diverse array capable of transmitting a beam of an arbitrary shape. The method includes the following steps that: a desired transmission beam shape in the rectangular coordinate system is set; the desired transmission beam shape in the rectangular coordinate system is converted into a polar coordinate system; a polynomial coefficient is obtained by means of polynomial fitting; phase terms caused by additional signals in the polar coordinate system are obtained; the transmission signals of each of the signal diverse array elements of the signal diverse array are obtained; the transmission signals of each of the signal diverse array elements are accumulated to an antenna radiation pattern under the polar coordinate system of the signal diverse array; and the antenna radiation pattern under the polar coordinate system is converted to an antenna radiation pattern under therectangular coordinate system.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a control method of a signal control array and a method for setting an antenna transmission pattern of a signal control array with beams of arbitrary shape in a polar coordinate system. Background technique [0002] The invention of Phased Array technology has a history of more than 100 years. By adjusting the phase or delay of each array element signal, the phased array can freely realize the spatial scanning of the beam without rotating the antenna, so it is widely used in radar, communication, broadcasting, radio astronomy, meteorology and other fields. However, the phased array maintains a constant transmit beam pointing during the transmit pulse time, which makes unwanted signals such as clutter and interference on the phased array transmit beam pointing to be easily received by the phased array, resulting in It is easily detected and jammed. [0003] By adjusting the frequency of ...
