中文说明：
阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。
English Description：
When the frequency increment between the elements increases logarithmically, the transmitted beam does not appear periodically according to the distance, and the maximum value of the transmitted beam pattern is only one. Compared with the traditional frequency diversity array with fixed frequency increment between array elements, log FDA can resist the range dependent interference, and transmit energy does not leak, so it has a certain low interception performance.
