Research On Active Phased Array Radar Wave Control Computing Unit

The beam steering system of active phased array radar takes the way of electric scanning instead of the mechanical scanning servo system of conventional radar,with features of flexible beam scanning,large airspace,strong anti-saturation capability and tracking multiple targets,it is gradually replacing the conventional scanning mechanical radar.As the core module of the beam steering system,arithmetic unit affects the performance of the phased array radar.In order to improve the flexibility,real-time performance,calculating speed and reduce the power consumption of arithmetic unit,the CORDIC(Coordinate Rotation Digital Computer)algorithm is used to replace the look-up table to calculate the wave code in this paper.In the design,the CORDIC algorithm is written in MATLAB to realize the sine and cosine calculation and the calculation of the beam steering codes.CORDIC algorithm for calculating the sine and cosine value and the calculation of the beam steering codes are implemented using Verilog HDL(Hardware Description Language).The CORDIC algorithm and the entire arithmetic unit module are simulated using the Modelsim simulation tool and verified by the FPGA(Field Programmable Gate Array),the results show that the design basically meets the requirements.By using the CSMC(Central Semiconductor Manufacturing Corporation)0.5um CMOS(Complementary Metal Oxide Semiconductor)technology and Cadence's Virtuoso,a full custom chip layout design is realized...
