影响CPHD滤波器的另一个限制是所谓的“诡异”效应[19]，这意味着当目标被误测时，其一些概率质量会转移到检测到的目标上，而不管它们的物理分离如何。
Another limitation affecting the CPHD filter is the so-called "spooky" effect [19], which means that when a target is misdetected, some of its probability mass is shifted onto the detected targets, regardless of their physical separation.
