常规假目标欺骗干扰产生的假目标数量有限，无法对雷达实施有效压制，密集假目标干扰可以使雷达无法锁定真目标，甚至出现信号处理饱和。本文论述了基于分段重构法的密集假目标干扰工作原理与数学模型，该方法没有大量的乘法运算，节省存储资源，最后通过仿真实验比较，验证了该方法的有效性。

By using conventional false target deception jamming approach, number of false targets can be generated is limited and can not carry out effective blanket jamming against radar. Dense false target jamming can make radar unable to lock on true targets, and even lead to signal processing saturation. Operational principle and mathemati-cal model of dense false target jamming based on compartmentalization and regroupment is addressed. This method does not need a large amount of multiplication operation, therefore storage space are saved. Simulation and experi-ment results have proved the validity of this method.
