Abstract：Conventional phased array radar transmits coherent signal to form antenna pattern. By transmitting and receiving antenna reuse its aperture is always less than MIMO radar. This paper firstly analyses the same points and the difference between MIMO radar and phased array radar. It further points out that the essential advantage of MIMO radar is the digital transmitting beam forming. Second it designs a diversity phased array radar in collision avoidance atmosphere. Its transmitting part uses phase array system, while the receiving part uses the Digital BeamForming (DBF). Through the analysis for the limitation of the digits phase shifter, it proves that this radar can achieve the same virtual aperture performance as MIMO radar, while the rader can avoid to produce the orthogonal signal. Finally through the computer simulation it verifies the feasibility and effectiveness of the method. This radar system can effectively reduce the cost and improve channel consistency under the premise of promised beam width.
