纳入了机械损伤和应变速率的断裂UMAT子程序，不能用于平面应力。(The fracture UMAT subroutine incorporating mechanical damage and strain rate can not be used for plane stress.)

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。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)
