Research and Analysis of Target Location Method Based on Improved Jacobi Algorithm

In the three-dimensional coordinate system, there are four omnidirectional antenna radar stations with fixed coordinates. These radar stations form a network radar and observe the target. In this paper, the beat signal with white Gaussian noise obtained by mixing the FMCW(Frequency Modulated Continuous Wave) transmission signal and the echo signal is processed by FFT to obtain the frequency value of the beat signal. Finally, the state information including the target distance obtained by the improved Jacobi iterative algorithm is compared and compared with the traditional Jacobi iterative algorithm. The simulation results were analyzed, and the superiority of the improved algorithm was verified, which provided help for accurate and timely meteorological observations.
