This paper deals with the algorithms for forming adaptive nulls of the sum and difference patterns in digital beamforming,and gives an outline of the approach to getting the sum and difference simultaneously.The effects of amplitude and phase errors in the intercoupling and receiving channels on the sidelobe and the adaptive nulling are discussed.A way that eliminates the effects of amplitude and phase errors is presented.It is proved that the weighting and the LMS algorithm can not be interchanged.

The requirements of storage capacity and computations for beamforming are greatly reduced, and error corrections become easier. Since all the information available at the array elements is preserved at the output of FFT processor, flexible antenna patterns can be obtained.

This paper discusses the way to decide the direction of a target by using DBF technique in the environment of interference and gives the simulation results. The sum and difference beams in the monopulse technique are used in direction finding of a target. Because of the errors in the amplitude and phase existing in each receiver, the null position in the steering direction will drift and the null depth will not be ideal, thus affecting the accuracy of direction finding. This paper presents a method by which a null can be produced in the ideal steering direction in the difference pattern to correct the null position and deepen the null depth. It can be seen that a new approach to accurate direction finding is available by using DBF technique. In addition, simulation results are given to show the effect of reject the main lobe interference on the sum and difference patterns.

本文讨论了在干扰环境中利用数字波束形成技术确定目标方向的方法,给出了计算机模拟结果。测量目标角度是基于单脉冲技术中的和差波束的方法。由于各路接收机幅相误差和算法本身的影响,差波束指向零点将产生漂移且零深不够理想,影响了测角精度。本文提出了在差波束的理想指向零点方向用正交化算法产生一零点的办法来校正零点漂移和加深零深,又不影响差方向图的其它性能,从而为用数字波束形成技术精密测角提出了一条路径。另外,本文给出了为消除主瓣干扰而对和差方向图影响的模拟结果。
