Problems solved by technology

Taking 36 reflector array elements as an example for simulation calculation, under the rectangular grid arrangement, the gain difference between the grating lobe and the main lobe is about 1dB. If the interference of the adjacent spacecraft enters through the grating lobe, it is easy to cause interference to the main lobe

Abstract

The invention discloses a distributed antenna layout optimization design method and system, and belongs to the technical field of antenna layout design, and the method comprises the following steps: S1, defining a solution space; S2, defining a fitness function; S3, initializing the random position and speed of a particle swarm; S4, gradually searching an optimum in the solution space; S5, updating the particle speed; S6, updating particle positions. By applying the particle swarm optimization, under the condition that the minimum unit spacing requirement is met, an array coordinate position serves as a variable, array arrangement is optimized, a reasonable and corresponding fitness function is designed, the gain difference between a grating lobe and a main lobe can be remarkably reduced, and therefore the effects of restraining the grating lobe and improving the anti-interference capacity of the system are achieved, and the method is worthy of being used and popularized.

Description

technical field [0001] The invention relates to the technical field of antenna layout design, in particular to a distributed antenna layout optimization design method and system. Background technique [0002] The new-generation ground station system uses a large number of small-caliber antennas for distributed array formation. If many reflector antennas are arranged in a regular regular grid, such as a rectangular grid or a triangular grid, the distance between the array elements is far beyond If the wavelength of the working frequency band is exceeded, multiple grating lobes will be generated near the main lobe, and the gain value is close to the main lobe. Taking 36 reflector array elements as an example to carry out simulation calculations, under the rectangular grid arrangement, the gain difference between the grating lobe and the main lobe is about 1dB. If the interference of adjacent spacecraft enters through the grating lobe, it is easy to cause interference to the ma...
