根据舰船螺旋桨噪声一书给出的计算空泡噪声的公式，简便计算各种条件下的螺旋桨噪声级的程序(According to the formula for calculating the cavitation noise given in the book "Propeller Noise of Ships", the program for calculating the propeller noise level under various conditions is simple and convenient.)

说明：  为了感谢惠俊英老师的谆谆教诲，特为好奇诸君再奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，又轻松跑完9份作业（9路招式），即悟简正波海洋声场传播模型之能耐！ KRAKEN与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对KRAKEN的原创。也感谢由Free Software凝聚起来的自由科学家社区。 本秘籍适合大三以上和非水声物理专业同志们的快速参学。 吴开明 2018.12(The KRAKEN model was initially developed as a research code to evaluate new algorithms. As such it required numerous modifications to be usable as a production code. This work was begun at the Naval Ocean Systems Center and continued at the Naval Research Laboratory in support of the research on matched-field processing.)

说明：  采用频移调制的方式产生RGPO干扰，并定量分析它对LFM体制雷达的影响效应。按照脉冲重复周期为间隔，完成了动态的RGPO干扰演示，对从事雷达电子战领域研究的技术人员有一定的参考。(RGPO jamming is produced by frequency shift modulation, and its effect on LFM radar is analyzed quantitatively. According to the interval of pulse repetition period, the dynamic RGPO jamming demonstration is completed, which has certain reference for the technical personnel engaged in the radar electronic warfare field.)

利用蒙特卡洛的方法进行威布尔参数估计，随机生成对应参数估计值，不断迭代达到需要精度(Weibull parameter estimation using Monte Carlo method.)
