The beam pattern of the antenna, which is a converter of the space electromagnetic wave and the system electric signal, characterizes the degree of bundling of the space electromagnetic wave radiated by the antenna. The beam pattern of the phased array antenna needs to have the capability of forming a specific shape and rapidly scanning the beam in a predetermined airspace, and each array element of the phased array antenna needs to be accessed into a phase and amplitude modulator (such as a phase shifter, an attenuator, a power amplifier and the like), and the amplitude and the phase of a transmission signal of each array element are controlled by a beam control system, so that the field distribution of an antenna port is changed, and the beam scanning of the phased array antenna is realized; the signals can be combined into one input and one output through a power synthesis and distribution network.
In the related art, for each array element of the phased array antenna, a plurality of phase and amplitude modulators are generally used to control the array element, and therefore, each array element needs to occupy a plurality of IO ports. When the structure of the phased array antenna is complex and the number of array elements is large, the number of occupied IO ports of the processor is huge, the complexity of system design is increased, and the hardware cost is high.

The second output port 120 of the controller module is configured to transmit a modulation signal, which is used to enable the modulation module to modulate the array elements of the phased array antenna to achieve a preset beam control target, for example, the modulation signal may be a phase shift control signal or a power control signal, and correspondingly, the modulation module may include a phase shifter or a power amplifier, and the modulation signal may respectively act on these components. Of course, in the embodiments of the present application, the specific circuit component composition in the modulation module is not limited, for example, in some embodiments, an attenuator and the like may be further included therein.
The latch is a level-triggered storage unit, the action of data storage transmission depends on the level value of an input enabling signal, and the output changes along with the data input only when the latch is in an enabling state, for example, the stored data is received and output when the input enabling signal of the latch is high level. In the embodiment of the present application, for each parallel latch, each parallel latch includes a first input port 210 and a second input port 220, wherein the first input port 210 of the parallel latch is connected to the second output port 120 of the controller module for receiving the modulated data; the second input port 220 of the parallel latch is connected to the output end of the decoder, and when the output end of the decoder outputs a high level, the modulation data can be transmitted to the modulation module connected to the output end of the parallel latch, so that the modulation of the transmission signal of the corresponding array element is realized.
Because there are a plurality of array elements in a phased array antenna, and each array element needs a corresponding modulation module to be responsible for modulation, the phased array antenna beam control device in the embodiment of the present application may be provided with a plurality of modulation modules and parallel latches, and the specific number may be 2 or more, which is not limited in the present application.
In some more specific embodiments, the controller module of the present application may be formed by any one or more processor chips including an MCU monolithic computer, an FPGA, a CPLD, a DSP, an ARM, and the like, for example, may be configured as a monolithic computer chip or an FPGA chip; the decoder module of the present application may include a variable decoder, where the variable decoder is a multi-output combinational logic circuit that changes n inputs into 2n outputs, and can meet the large-scale circuit gating requirement, and in the embodiment of the present application, the number of pins of the output terminal of the selected variable decoder may be greater than 10; the model of the parallel latch can be selected to be an SN74HC573 chip which is a high-performance device, low-level data latch and high-level data output.

The methods set forth in the examples of the present application are explained and illustrated below in conjunction with the above description. It should be noted that, for the step numbers in the following embodiments, the step numbers are set for convenience of illustration only, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.
Referring to fig. 2, the method mainly comprises the following steps:
in this embodiment of the present application, when performing beam control on a phased array antenna, a modulation signal and target array element information corresponding to the modulation signal may be input to the control device through a baseband. Where the modulation signal is used to control the beam of the antenna, for example, in some embodiments, the modulation signal may include at least one of a phase shift control signal, an attenuation control signal, or a power amplification control signal. The target array element information is used for characterizing the array element corresponding to the modulation signal, that is, the modulation signal is used for modulating which array element of the phased array antenna.
In the embodiment of the application, after receiving the modulation signal and the target array element information corresponding to the modulation signal, the target gating signal corresponding to the decoder can be determined according to the target array element information, because the output end of the decoder is connected with a modulation module, and each modulation module is correspondingly used for modulating an array element, therefore, according to the target array element information, which output pin of the decoder needs to trigger a high level can be determined, and thus the target gating signal corresponding to the decoder can be determined.
And step 130, outputting the modulation signal and the target gating signal to the controller module to modulate a transmission signal of an array element of the phased array antenna.
In the embodiment of the application, the modulation signal and the target gating signal can be input into the controller module, so that the controller module can control the decoder module to act according to the target gating signal, and the gated output of the output end of the decoder is realized, so that the corresponding parallel latch acts; the modulation signal can be transmitted to each parallel latch in a parallel transmission mode, when the parallel latch corresponding to the target gating signal acts, the modulation signal can be transmitted to the modulation module connected with the modulation signal, and the modulation module can complete modulation on the transmission signal of the array element of one phased array antenna according to the modulation signal.
In some embodiments, the control method of the present application may further include the steps of:
scanning modulation states of array elements of the phased array antenna;
and when all array elements of the phased array antenna are modulated, stopping the modulation of the phased array antenna.
Generally, each time the phased array antenna is modulated, all array elements need to be modulated once to complete the beam control of the phased array antenna immediately. Therefore, in the embodiment of the application, the modulation states of the array elements of the phased array antenna can be scanned, when all the array elements of the phased array antenna are modulated, the modulation of the phased array antenna is stopped, namely, the modulation process of beam control is completed, and normal operation can be started.
The following describes advantages of a phased array antenna beam steering method provided by the present application with reference to a specific embodiment.
Referring to fig. 3, fig. 3 shows an array schematic diagram of a phased array antenna, which has 52 array elements, and assuming that for each array element in the phased array antenna, a 6-bit digital phase shifter and a 7-bit digital attenuator are required for modulation, the modulation module of each array element needs 13 IO ports to transmit modulation data. If according to conventional design, adopt the singlechip to receive the modulation signal of baseband equipment promptly, then send modulation signal to FPGA (having utilized the advantage that FPGA device IO mouth is many in quantity), forward modulation module again and carry out the control of phase shifter and attenuator, then need occupy 52 x 13 altogether 676 FPGA's IO mouth, not only the work load of development, installation is big, has also increased the cost of device, and the power consumption of control panel will rise in addition.
By adopting the control method in the embodiment of the application, a 16-bit latch can be set for each array element, 13 control signals which are output by the single chip microcomputer and aim at a 6-bit digital phase shifter and a 7-bit digital attenuator are simultaneously connected to the input port of the latch corresponding to each array element, and the output port of the latch is connected to the specific phase shifter and attenuator of each antenna array element. Meanwhile, 6 IO ports of the single chip microcomputer are used for controlling one decoder, and the decoder can realize the gating of 64 channels. The gating signal of the decoder is connected to an LE pin of a latch of each array element, when the LE pin is gated, the modulation signal of an input port of the latch is output to a pin of an output port of the latch, so that the phase shifter and the attenuator are enabled to act, and when the gating signal is not gated, the latch keeps the last output signal. So, to the singlechip, only need 13+6 become 19 IO mouths alright in order to realize beam control, the treater IO mouth quantity that can greatly reduced system relied on to can reduce the hardware equipment cost and the development cost of system, and the whole complexity of system, consumption are lower.
