Problems solved by technology

However, this method relies on receiving external weight input for weighting calculations, and does not involve the real-time calculation function of multi-beam weights. The real-time flexibility of beam control is not high enough, and it does not involve anti-interference measures.

Embodiment

[0190] In this example, the front has 4×4=16 array elements, and the maximum number of beams N that can be formed within the constraints of FPGA resources max for 16. At a certain moment, the radar needs to form four directional beams at the same time, working in the anti-jamming mode S2.

[0191] Step 1: Scheduling frame protocol information input and frame analysis

[0192] When the FPGA is powered on, all registers are set to 0 by default, and the FIFO and RAM are empty, which is consistent with the state after reset.

[0193] Enter a frame beam followed by a new command. The frame structure is defined as 20 bytes, the first to second bytes are the frame header length=0x14, the third byte is the function code Fcode=0x10, the fourth byte is the number of beams K=0x04, the fifth to The 6 bytes are the azimuth and elevation angles of the first beam respectively. The 7th to 8th, 9th to 10th, and 11th to 12th bytes are the azimuth and elevation angles corresponding to the se...

Abstract

The invention belongs to the technical field of array signal processing, and in particular relates to an FPGA-based controllable multi-beam forming method. The present invention proposes an FPGA-based controllable multi-beam forming method, which can control and generate corresponding beam data according to the input angle of the scheduling frame protocol. It also integrates conventional beamforming and adaptive beamforming functions. Adaptive beamforming solves beam weights in an iterative manner, avoids covariance matrix inversion operations, and improves real-time calculation of weights. The iterative module is versatile. Multi-beam weight calculation can be done with this method. The weighted output terminal performs multi-beam weighting in a parallel pipeline to generate beams pointing at desired angles.

Description

technical field [0001] The invention belongs to the technical field of array signal processing, and in particular relates to an FPGA-based controllable multi-beam forming method. Background technique [0002] In order to expand the scanning range of airspace and improve the detection efficiency of phase-scanning targets, phased-array radar can adopt simultaneous multi-beam forming technology. The FPGA-based DBF design has the advantages of high data processing parallelism, fast computing speed, and small hardware size, and is suitable for multi-beamforming processing large-scale arrays. [0003] Liu Ying, Wei Wei and others designed a general-purpose DBF module for two-dimensional beamforming in "FPGA-based large-scale two-dimensional area array digital beamforming", mainly weighting the weight coefficients in a serial pipeline, which can be Save multiplier resources and improve module reuse. However, this method needs to calculate the amount of module multiplexing and bea...
