Abstract
Description
Technical Field
[0001] The present invention relates to the field of beam direction control, and in particular to a high-power electromagnetic signal directional radiation control system with controllable beam direction. Background Art
[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
[0003] Beam steering is a crucial component of electromagnetic signal radiation. There are two primary approaches to achieving beam steering: mechanical scanning through mechanical structures and electronic scanning using phased array antennas. Phased array antennas are gaining increasing attention. A phase-steering array antenna, consisting of several independent antennas or radiating elements, can alter the radiation characteristics of the entire phased array by adjusting the feed phase of each element.
[0004] Currently, high-power beam steering primarily relies on mechanical scanning. Mechanical structures have slow response times, take up space, and increase weight. Overall, mechanical structures lack flexibility and are difficult to transport and install. Summary of the Invention
[0005] The purpose of the present invention is to address the problems of slow response speed and bulky structure of current high-power electromagnetic radiation processing devices, and to provide a high-power electromagnetic signal directional radiation control system with controllable beam direction. Compared with traditional equipment, the mechanical structure is reduced and the response speed is greatly improved. Within the reachable range of the beam, the switching rate can reach milliseconds, thereby solving the above problems.
[0006] The technical solutions of the present invention are as follows:
[0007] A high-power electromagnetic signal directional radiation control system with controllable beam direction, comprising: a beam controller, a power amplifier, a waveguide switch and a horn antenna;
[0008] The RF signal output by the signal source is sent to the beam controller. The RF signal is output in multiple channels through the internal multi-channel power divider. After the phase of each RF signal is adjusted by the digital phase shifter, the output RF signal enters the multi-channel power amplifier for power amplification and output. By controlling the channel selection state of the waveguide switch, the polarization mode of the output signal can be selected.
[0009] Furthermore, the beam controller includes: an ARM single chip microcomputer, a configuration instruction parsing module, an array element phase solver module and a channel phase compensation module;
[0010] The ARM single chip microcomputer is responsible for receiving the parameter information sent by the control computer and passing the parameter information to the array element phase operator module through the configuration instruction parsing module;
[0011] The channel phase compensation module reads the phase compensation data phase_initial of each channel stored in the external Flash;
[0012] The array element phase operator module calculates the phase control code of each digital phase shifter according to the parameter information and the phase compensation data phase_initial of each channel, drives the phase shifter to adjust the phase, and realizes the beam direction change control.
[0013] Furthermore, the parameter information includes: signal frequency, beam direction and polarization state parameters.
[0014] Furthermore, the beam controller further comprises: a waveguide switch state acquisition module, a state framing submodule, an SPI communication interface driver module and a waveguide control module;
[0015] The ARM single chip microcomputer is responsible for receiving the parameter information issued by the control computer and transmitting it to the configuration instruction parsing module through the SPI communication interface driver module;
[0016] The waveguide switch status acquisition module collects the current channel status of the waveguide switch, reports the current antenna polarization working status, and returns status frame data through the status framing submodule. The status frame data is transmitted to the configuration instruction parsing module through the SPI communication interface driver module. The configuration instruction parsing module configures the frame data and finally drives the waveguide switch to perform switching action through the waveguide control module.
[0017] Furthermore, the beam controller further includes: a memory read-write control module; the channel phase compensation module reads each channel phase compensation data phase_initial stored in the external Flash through the memory read-write control module according to the array element coordinate data.
[0018] Furthermore, the calculating of the phase control code of each digital phase shifter includes:
[0019] Calculate the phase adjustment value phase_set for each channel based on the polarization mode, signal frequency, and beam pitch direction;
[0020] The phase adjustment value phase_set of each channel is added to the phase compensation data phase_initial parameter of each channel to calculate the phase control code.
[0021] Compared with the existing technology, the beneficial effects of the present invention are:

[0040] Calculate the phase adjustment value phase_set for each channel based on the polarization mode, signal frequency, and beam pitch direction;
[0041] The phase adjustment value phase_set of each channel is added to the phase compensation data phase_initial parameter of each channel to calculate the phase control code.
