【摘要】：MIMO (Multiple Input Multiple Output)雷達是一種新型雷達,MIMO的技術引自于通信技術,在雷達領域一經(jīng)提出就受到廣泛關注,雖然MIMO雷達在實際應用中還有很多問題要考慮,但是作為新型高性能雷達,對MIMO雷達的深入研究有很大意義。 本文首先對MIMO雷達的概念和國內(nèi)外發(fā)展動態(tài)做了簡單描述,研究共址式和統(tǒng)計式兩種形式的MIMO雷達,分別對比優(yōu)缺點,并描述MIMO雷達作為測量雷達的優(yōu)越性。接下來討論MIMO雷達發(fā)射波形的正交性能,從相關特性方面分別給出正交頻分復用-線性調(diào)頻信號、二相編碼信號、隨機多相碼信號等的仿真對比圖。然后分析MIMO雷達的信號處理流程,用MUSIC和Capon算法對目標進行角度估計,發(fā)現(xiàn)MUSIC算法的測角精度比Capon算法高,但是計算量大。之后對比稀疏布陣情況下兩種算法對于目標參數(shù)估計的差異,同時針對高速運動目標給出探測方法,避免高速運動目標距離走動的現(xiàn)象。最后基于接收分集MIMO雷達分析多目標情況下的定位技術,完成目標定位并畫出定位精度分析圖。 本文利用MATLAB對所述理論進行驗證仿真,驗證了本文所涉及到的雷達數(shù)據(jù)處理的正確性。
[Abstract]:MIMO / multiple Input Multiple Output) radar is a new type of radar, which is introduced from the communication technology. It has attracted extensive attention once it has been put forward in the radar field. Although there are still many problems to be considered in practical application of MIMO radar, as a new type of high performance radar, it is a new type of high performance radar. The research on MIMO radar is of great significance. In this paper, the concept of MIMO radar and its development at home and abroad are briefly described in this paper. Two types of MIMO radar, coaddress radar and statistical radar, are studied. The advantages and disadvantages of MIMO radar as measurement radar are compared, and the advantages of MIMO radar as measurement radar are described. Then the orthogonal performance of MIMO radar transmitting waveform is discussed, and the simulation contrast diagrams of orthogonal frequency division multiplexing linear frequency modulation signal, two-phase coded signal, random polyphase code signal and so on are given respectively from the correlation characteristics of the quadrature frequency division multiplexing (OFDM) signal and the linear frequency modulation signal (LFM). Then the signal processing flow of MIMO radar is analyzed, and the angle estimation of the target is carried out by MUSIC and Capon algorithms. It is found that the angle measurement accuracy of MUSIC algorithm is higher than that of Capon algorithm, but the calculation amount is large. Then the difference between the two algorithms in the case of sparse array is compared. At the same time, the detection method for the high speed moving target is given to avoid the phenomenon of moving range of the high speed moving target. Finally, based on the receiver diversity MIMO radar analysis of the multi-target positioning technology, the target location is completed and the positioning accuracy analysis diagram is drawn. In this paper, MATLAB is used to verify the theory and verify the correctness of the radar data processing involved in this paper.
