Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment resource scheduling based on a resource pool architecture, and in particular to a resource management device and method for a phased array system with a resource pool architecture. Background Art

[0002] Resource pooling is a concept widely used across multiple fields. Its primary goal is to centrally manage and dynamically allocate resources, thereby improving resource utilization efficiency, flexibility, and scalability. Integrating dispersed resources into a unified resource pool facilitates centralized management and monitoring, allowing for flexible and efficient scheduling based on task requirements.

[0003] Electronic equipment systems based on large phased arrays typically include a significant number of hardware modules and extensions to perform various functions, from space signal transmission and reception to data information processing. For example, phased array antenna systems are used for space signal transmission and reception, general signal processing platforms are used for baseband signal processing, and computer platforms are used for data processing and various display and monitoring functions. To better schedule and manage various system resources and achieve rapid response to tasks, various hardware resources can be classified, managed, and virtualized. Through virtualization, hardware resources are transformed into various functional modules, decoupling tasks from the underlying hardware. These virtualized functional modules are then managed and monitored in a resource pool. Transforming the hardware resources of electronic equipment systems into multiple resource pools composed of various functional modules can greatly improve system integration, task reliability, and resource flexibility. For example, the Chinese invention patent application with publication number CN112700172A, "A Flexible Design Method for a Broadband Passive Phased Array Resource Scheduling Framework," counts the resources that a passive phased array radar may have, virtualizes each resource, and places it into a virtual resource pool. The method then modifies the resource data in the virtual resource pool accordingly based on different passive phased array radar design requirements. However, the method does not provide a method for establishing, maintaining, or deleting interconnections between multiple virtualized resource pools. Summary of the Invention

Information interaction between multiple virtualized resource pools is achieved.

[0098] In addition, complete the task plan in the integrated operation management module p After the required resources and links are configured, the beam resource pool management module monitors the transmit beam set SetTBeam p and receive beam set SetRBeam p The health status of the resource elements in the baseband resource pool management module monitors the modulator set SetMod p and demodulator set SetDeMod p The health status of the resource elements in the computing resource pool management module monitors the computing resource demand set SetVirPC p The health status of the resource elements in the matrix. When an element fails, the integrated operation management module will set all the rows or columns in the corresponding interconnection matrix to zero, and the task execution will fail, which can realize the monitoring of task resources.

[0099] In Task Scheduler p After the task is completed, the integrated operation management module notifies the beam resource pool management module, baseband resource pool management module, and computing resource pool management module to release resources and interconnect the matrix M V→M 、M M→T 、M R→D and M D→V Setting all elements in to zero can release network transmission resources.

[0100] The beam resource pool management module is capable of scheduling and managing the beam resource pool, and includes: a transmit beam resource pool beam synthesis device and a receive beam resource pool beam synthesis device, wherein the transmit beam resource pool beam synthesis device includes:

[0101] The transmit beam resource pool management module is used to periodically send the beam pointing direction of the managed transmit beam and the required beam EIRP: EIRP is the equivalent isotropic radiated power (Equivalent Isotropic Radiated Power);

[0102] The array resource management module is used to adaptively schedule subarrays based on the beam pointing of each transmit beam and the required beam EIRP. When the angle between the subarray normal pointing and the beam pointing is less than or equal to the set angle and the sum of the subarray EIRP is greater than or equal to the required beam EIRP, the transmit beam in the specified direction is synthesized. The scheduled subarrays constitute the subarray set S i (t), the calculation formula for the sum of the sub-array EIRP is:

[0103] G k is the sub-matrix set S i The normal gain of the kth sub-matrix in (t), P k is the sub-matrix set S i The transmission power of the kth subarray in (t), θ k (t) is the sub-matrix set S i The angle between the normal of the kth subarray in (t) and the beam direction, K is the subarray set S i (t) The total number of neutron arrays, 1≤k≤K.

[0104] The transmit beam resource pool management module manages I(t) transmit beams at time t, and the i-th transmit beam is denoted as TBeam i , i∈[1,I], I represents the transmit beam TBeam i The total number of transmit beams TBeam is periodically updated by the transmit beam resource pool management module according to the beam update period. i The beam pointing and the required beam EIRP are sent to the array resource management module, which divides the M planar sub-arrays on the array into an idle sub-array set S idle (t) and the set of working sub-arrays S busy (t), the surface used to synthesize the transmit beam TBeam i The planar submatrix of the submatrix set S i (t), different transmit beams do not share a plane sub-array, the working sub-array set S busy (t)=S1(t)∪S2(t)∪...∪S I(t) (t).

[0105] See Figure 3 and 4 The process of adaptively scheduling the sub-arrays by the array resource management module according to the beam pointing of each transmit beam and the required beam EIRP includes:

[0106] Step 1: At time t+Δt, Δt represents the transmit beam update period, the array resource management module determines the transmit beam TBeam i Is the task finished? If so, set the subarray S i(t) The sub-array is released. If it is not finished, the idle sub-array set S is maintained. idle (t) and the set of working sub-arrays S busy (t) unchanged;

[0107] Step 2: Select the idle sub-array set S idle (t) Extract K continuous distribution sub-matrices A k Constitute the sub-matrix set S i (t+Δt), update the idle sub-array set S iale (t+Δt) and the working sub-array set S busy (t+Δt);

[0108] Step 3: Determine sub-array A k The normal direction and the beam pointing direction of the transmitted beam Is the angle between them less than or equal to the set angle? If so, go directly to step 4. If not, change sub-array A k From the sub-matrix set S i Delete (t+Δt) and go to step 4;

[0109] Step 4: Determine the sub-array set S i Is the sum of the sub-array EIRP at (t+Δt) greater than or equal to the beam EIRP? i (t+Δt), if so, based on the sub-array set S i (t+Δt) synthesizes the transmit beam; if not, select the idle sub-array set S idle (t+Δt) selects the sub-array set S i (t+Δt) adjacent sub-matrix A p , when sub-matrix A p Normal and beam pointing The angle between them is less than or equal to the set angle, and the sub-array A p Put into the sub-matrix set S i (t+Δt), get the updated sub-matrix set S i (t+Δt), repeat this step until the updated sub-array set S is satisfied i The sum of the sub-array EIRP at (t+Δt) is greater than or equal to the beam EIRP i (t+Δt), based on the updated sub-matrix set S i (t+Δt) synthesized transmit beam.

[0110] In step 1, determine the transmit beam TBeam i Whether the mission is completed is determined by judging the beam EIRP i Is (t+Δt) equal to 0, 1≤i≤I(t+Δt), if EIRP i (t+Δt)=0, determine the transmit beam TBeam iAfter the task is completed, the array resource management module sets the sub-array S i (t) is released, that is, S idle (t+Δt)=S idle (t)∪S i (t), and reduce the number of managed transmit beams by I(t+Δt)-I(t); if EIRP i (t+Δt)>0, determine the transmit beam TBeam i The task is not completed, the array resource management module maintains the idle sub-array set S idle (t) and the set of working sub-arrays S busy (t) remains unchanged.

[0111] In step 2, update the idle sub-array set S idle (t+Δt) and the working sub-array set S busy (t+Δt) means: from the idle sub-array set S idle (t) delete the sub-array set S i (t+Δt) gets the idle sub-array set S idle (t+Δt), and in the working sub-array set S busy (t) Add sub-array set S i (t+Δt) to get the working sub-array set S busy (t+Δt).

[0112] The setting angle of the present invention is 60 degrees, by judging the sub-array A k Normal and beam pointing Is the angle between them less than or equal to 60°? If it is less than or equal to 60°, it means that subarray A k The efficiency of participating in beam synthesis is greater than half and has not been attenuated to half. If it is greater than 60°, it means that the sub-array A k The angle between the normal direction of the composite beam and the direction of the composite beam is too large, so the sub-array A k Only half of the power can be contributed to the total beam, and the efficiency is only 50%. Therefore, it does not participate in the transmit beam synthesis. k Normal and beam pointing By adjusting the angle between the two sub-arrays, the system efficiency can be improved by selecting the sub-array with larger power contribution to participate in the transmit beam synthesis.

[0113] In step 3, determine sub-array A k The normal direction and the beam pointing direction of the transmitted beam The process of determining whether the angle between them is less than or equal to the set angle includes:

[0114] 3.1、M planar sub-arrays form a transmitting phased array system. With O as the origin, a global Cartesian coordinate system O-XYZ is established. kEstablished with O k The sub-array Cartesian coordinate system O is the origin k -X k Y k Z k , the X of the coordinate system k O k Y k Plane and submatrix A k Coplanar, O k Z k Pointing to subarray A k Normal direction;

[0115] 3.2 Subarray A k Normal and beam pointing The angle between them is θ k (t+Δt), calculate cosθ k (t+Δt), when Go to step 4, when A k From the sub-matrix set S i (t+Δt) is deleted and the idle sub-array set S is updated idle (t+Δt) and the working sub-array set S busy (t+Δt);

[0116] in, (x k ,y k , z k ) is the sub-matrix A k Origin O k The coordinates in the global Cartesian coordinate system O-XYZ, (x′ k , y′ k , z′ k ) is the sub-array level Cartesian coordinate system O k -X k Y k Z k The coordinates of the lower point (0, 0, 1) in the global Cartesian coordinate system O-XYZ, Represents submatrix A k The unit vector in the normal direction, The unit vector that represents the direction of the resultant beam.

[0117] The transmit beam resource pool beamforming device, based on a collection of subarrays (rather than processing each antenna element independently), schedules different subarrays for beamforming based on different beam pointing directions. It also schedules the smallest subarray for beamforming based on mission requirements, rather than all subarrays, to improve array efficiency. While meeting the beam's equivalent isotropic radiated power (EIRP) requirement, it achieves the minimum cost (minimum array size) for synthesizing a beam in a specified direction, minimizing system power consumption. During mission execution, the device adaptively schedules subarray resources by determining the angle between the subarray normal and the desired synthesized beam, as well as the subarray's own EIRP (comprised of subarray gain (dB) + subarray power (dBW)). This allows for efficient subarray resource scheduling for large multi-faceted phased arrays or large conformal phased array systems based on subarray splicing, fully leveraging the flexibility of multi-faceted or conformal phased array systems to synthesize beams based on transmit power requirements and achieve optimal power efficiency.

[0130]

[0131] in When ηm When it is less than or equal to the set threshold, the sub-array m is removed from the sub-array set S i (t); otherwise, put the sub-matrix m into or leave it in the sub-matrix set S i (t), get the updated sub-matrix set S i (t).

[0132] In step 2, the normal vector of the sub-array m and the receiving beam RBeam i (t) direction vector The inner product of is calculated as:

[0133] in, is the unit vector in the normal direction of sub-matrix m,

[0134] Set the threshold to 0, that is, when the sub-array attenuation factor η of sub-array m m >0, then put the sub-matrix m into the sub-matrix set S i (t), that is, sub-array m participates in receiving beam Beam at time t i (t) formation.

[0135] The process of synthesizing the subarray beam based on the updated subarray set includes:

[0136] 1.1. The updated sub-array set S is scheduled by the sub-array resource management module i (t) in the K sub-arrays, calculate the antenna units in the k-th sub-array in the sub-array coordinate system O k -XYZ coordinates (x′ k,n ,y′ k,n ,z′ k,n ):

[0139]

[0140] 1.3. Calculate the weighted vector of the kth sub-matrix And based on the weighted vector, a subarray beam RBeam is formed i (t,k).

[0141] The subarray resource management module calculates the updated subarray set S i The geometric center of (t) Calculate the time delay difference Δτ of the kth subarray relative to the geometric center k , and the sub-array beam RBeam formed by the k-th sub-array i (t,k) performs time delay compensation to obtain the compensated sub-array beam RBeam i (t-Δτ k ,k), the sub-array resource management module is based on the updated sub-array set S i (t) Complete receiving beam RBeam i (t) synthesis.

[0142] Among them, the updated sub-array set S i The geometric center of (t) The calculation method is:

[0143] Among them, K is the sub-matrix set S i The number of subarrays in (t).

[0144] Receive beam RBeam i The calculation method of the synthesis of (t) is:

[0145] Among them, Beam i (t-Δτ k ,k) is the compensated sub-array beam, η k is the sub-matrix attenuation factor of sub-matrix k.

[0146] At time t+T, where T is the receive beam update period, the receive beam resource pool management module updates the i-th receive beam RBeam i The directional information of (t) is and will point to the information Send it to the sub-array resource management module, and the sub-array resource management module updates the sub-array set to S i (t+T), calculate the sub-matrix set S i (t+T) relative to the sub-matrix set S i The delay difference introduced by the change of (t) relative to the origin of the global coordinate system O has an impact on the received beam RBeam i (t+T) delay compensation is performed until the synthesis of all receiving beams in the beam resource management module is completed.

[0148]

[0149] in, is the sub-matrix set S i The geometric center of (t+T) c is the speed of light.

[0150] The receive beam resource pool beamforming device optimizes the scheduling of receive subarray resources based on the receive beam pointing direction, maximizing the receive beam gain. For non-planar receive phased arrays composed of multiple subarrays, beamforming estimates and compensates for the time delay introduced by the different phase centers between different subarrays, as well as the time delay introduced by the difference between the subarray phase center and the system phase center. This fully leverages the flexibility of multi-faceted or conformal phased array systems based on multiple subarrays to maximize receive aperture efficiency. This enables flexible subarray resource scheduling, subarray-system delay compensation, and multi-subarray beamforming for non-planar receive phased array systems. Furthermore, the introduction of subarray attenuation factors maximizes the conformal array's spatial coverage capability and reduces the impact of multi-faceted array phase center variations on beamforming.
