英语翻译通过调整k1的值可以调节在一定范围内调节有源单元数目.对于密度加权阵,k1的值不可以超过1,否则方向图将恶化.为有源阵元上的馈电幅度.若 只等1,密度加权阵为等副馈电,即用纯密度来模拟不等幅.这是一种简单的密度加权阵.为了进一步实现低副瓣,也可以不采用等幅度馈电,即多阶量化.例如,二阶量化,阵面中部单元的馈电幅度为1,阵面边缘的馈电幅度为0.5.通过多阶量化确定的密度加权阵,有源单元阵元的分布均匀,比等幅度馈电更容易实现低副瓣,这是一种多阶量化的复合型密度加权阵.

看来晚了一步
不过我赞同bluesboy23

By adjusting the value of k1 can be adjusted within a certain range adjust the number of active units. For the density weighted array, k1 values must not exceed 1, otherwise the pattern will deteriorate.
On the active array element for the feed rate. If only such a density of weight matrices for the other deputy feed, which range from pure to simulate the density increase. This is a simple weighted density matrix. In order to achieve low side lobe, or not fed with equal amplitude, that is multi-stage quantization. For example, the second-order quantification, the central front range of the feed unit 1, front edge of the feed rate is 0.5. Determined by the density of multi-stage quantization weighting matrices, active cell array element distribution, feed rate than the other is easier to achieve low side lobe, which is a multi-stage compound to quantify the density-weighted array
