摘　　要：面向多星测控应用提出了一种发射多波束形成方法,采用在数字基带进行多波束加权的处理方法,并联合正交投影算法,实现了独立可控的发射多波束形成,使各波束之间具有较高的隔离度。通过计算机仿真,对发射多波束的方向图性能以及各波束之间隔离度进行了性能分析,验证了该方法的可行性及有效性。The paper proposes a method of transmitting multi-beam formation for multi-satellite TTC.The method carries through multi-beam weighting in the digital baseband and incorporates orthogonal projection algorithm.It realizes independent controllable transmission of multi-beam formation,which provides high isolation between the beams.With computer simulation,pattern performance of transmitting multi-beam and isolation between beams are analyzed and the feasibility and validity of the technique is verified.
