Problems solved by technology

However, there are also some problems in the frequency control array, that is, after the spatial energy of the frequency control array is compressed into a focal band, from figure 2 It can be seen that this is an irregular focal zone, and the accuracy of the distance calculation for the position in the radar target detection system is low

Abstract

The invention discloses a target detection method based on a space energy focusing technology. By constructing a rectangular time-invariant space point focusing frequency control array structure and applying the rectangular time-invariant space point focusing frequency control array structure to a detection system to detect a target, space energy can be effectively compressed on different programs, the space energy in an interference band is improved, and therefore, the accuracy of target detection is effectively improved. The rectangular time-invariant space point focusing frequency control array provided by the invention has a wide prospect in the aspect of radar detection, can explore more array structures based on the structure, is widely used in radar and wireless communication, and has strong practicability.

Description

technical field [0001] The invention belongs to the technical field of microwave radar and wireless communication, and in particular relates to the design of a target detection method based on space energy focusing technology. Background technique [0002] Array antenna technology is widely used in the fields of radar, wireless communication, sonar and navigation. According to the needs of practical applications, antennas can be arranged in different ways. The most basic ones can be divided into linear array and area array. Compared with a single antenna, an array antenna can realize functions such as beam scanning, beam forming, and multi-beam. Researchers at home and abroad often conduct performance and application research according to the functional classification of array antennas, such as phased array antennas, frequency scanning antennas, adaptive antennas, and multiple-input multiple-output antennas (MIMO). In recent years, new arrays derived from phased arrays and ...
