Embodiment Construction

[0034] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0035] A simultaneous multi-beam selection switch for multi-target search and tracking, its principle block diagram is as follows figure 1 As shown, including: 40 1-to-2 power dividers and 8 10-to-1 switches. Using this multi-beam selection switch can simultaneously form 2 beam groups, each group has 4 beams. The flexible scheduling of beam groups can realize three working modes: full search, search+tracking, and full tracking.

[0036] The 40 power dividers receive 40 radio frequency signals sent by the Rotman lens, and one of the power dividers divides one of the radio frequency signals into two. In this way, ...

Abstract

The invention discloses a simultaneous multi-beam selection switch for multi-target search and tracking, including N power splitters and M P-selection 1 switches, where M is less than N, and each power splitter receives a transmission from a Rotman lens The radio frequency signal of the channel is divided into S channels, thereby forming S groups of N channel radio frequency signals, and the S group of N channel radio frequency signals is sent to M P selection 1 switches, P=S*N / M, the P The select 1 switch is divided into S groups, each group of switches receives a corresponding group of N signals, and the same group of radio frequency signals are sent to different P select 1 switches, and each P select 1 switch selects one of them as the output, thus forming a simultaneous M beams are output, and the M beams are divided into S groups, and each group has M / S beams. The invention has the following advantages: the amount of processing equipment is reduced, the scheduling of multiple beam groups can be independently performed, the flexibility of beam scheduling is guaranteed, and the system has the characteristics of modularization and scalability.

Description

technical field [0001] The invention relates to the technical field of phased arrays, in particular to a multi-beam selection switch for multi-target search and tracking. Background technique [0002] Phased array system has been paid more and more attention because of its high reliability, flexibility and good repeatability. The phased array system can realize simultaneous multi-beam parallel operation, and each beam has a different direction. Through the selection and scheduling of multiple beams, the scanning of different airspaces and the search and tracking of targets in different azimuths can be realized. At present, relatively mature phased array technologies include broadband digital array technology and analog array technology. [0003] The beamforming and scheduling of wideband digital array technology are carried out in the digital domain, which has the characteristics of high flexibility. However, with the increase of instantaneous processing bandwidth, the am...
