以“贴近纳新”理念改进 任职教育军事专业课教法的几点思考

深化以任职教育为主体的教学方法改革,是顺应当前武警部队职能任务多样化的必然要求。任职教育适应岗位任职能力的需要必须注重加强军事专业课教学方法的改革与探索。“贴近纳新”把贴近职能需要纳入教学理念、贴近任职实际纳入组教模式、贴近岗位实用纳入课题施教为着眼点,旨在适应任职教育岗位任职能力培养的需要。     

浅谈武警院校教学改革中互动式教学法的应用

互动式教学是武警院校教育改革中倡导的一种新型的教学模式,要正确应用互动式教学模式,就要注重互动双方的定位、互动问题的选取、互动方法的选择。     

一种时频混叠的欠定混合通信信号盲分离算法

针对衰减-延迟欠定混合通信信号的盲分离问题,提出了一种基于子空间最小距离的源信号估计算法,通过计算观测信号到混合矩阵列矢量张成子空间的距离,估计任意时频点同时存在的源信号数目以及当前源信号对应的混合矩阵列矢量,把欠定混合问题转化为超定问题,然后通过计算Moore-Penrose逆矩阵求解源信号,理论分析和仿真结果验证了算法的有效性。     

基于垂直线列阵的深海被动目标定深误差

首先研究了在深海环境下,采用三阵元垂直线列阵水声探测系统进行被动目标定深的基本原理。然后分别从随机误差、阵元配置偏差和相干多途水声信道干扰的角度,对被动目标定深的误差源进行了理论分析,并推导了相关公式。通过仿真实验,总结出各误差源对被动目标定深精度影响的规律,为进一步开展被动目标定深研究、提高被动目标定深精度奠定了基础。     

Regular and irregular forces in conflict: nineteenth century insurgencies in South America

ABSTRACT

In the decades following independence from Spain, ‘civil wars’ ravaged the newly established polities in South America. Former vice-regal capitals inherited a larger portion of the colonial administration and had larger economic resources and a hegemonic project they were able to have permanent and professional armed forces, capable of leading the offensive and giving battle following the European rules of military art. The central hypothesis of this work is that there is a necessary relationship between the shape of these asymmetrical conflicts, their outcome and the political territorial configuration of each country in post-revolutionary Spanish America. When permanent armies took over from local militias, the capital kept the integrity of its territories and there was a tendency towards political centralization. When this did not happen and the militias managed to find a way to defeat their centralizing enemies, the local powers had an opportunity to renegotiate their participation in the political body, and sought to maintain their independence, which was manifest in federal agreements, otherwise a process of territorial fragmentation began. More than a difference between regular and irregular forces there was one between intermittent, and permanent mobilization.     

Military Off the Shelf Procurements: A Norwegian Case Study

Buying off the shelf procurements (OTS) has become an important part of the national acquisition strategy in several countries, and this paper seeks to bring empirical evidence on OTS as the preferred acquisition strategy by use of data from 2015 to 2022 investment portfolio of the Norwegian Armed Forces. We develop definitions for three categories of procurement – OTS, modified OTS and development projects – as well as a method to classify projects into these categories. Our first finding is that the characteristics of OTS projects correspond to modified OTS and development projects. Our second finding indicates that OTS projects perform better when it comes to the completion of projects according to the initial schedule, compared to development projects.     

一种改进方位向非线性CS大斜视角SAR成像算法

大斜视角SAR成像时存在严重的距离走动现象,慢时域的距离走动校正在解决这一问题同时导致了聚焦深度问题.分析了二维频域解耦合后残余相位误差以及时域走动校正后的多普勒调频率误差,提出一种改进的方位向非线性CS算法,校正了三次以上距离迁徙带来的相位误差,同时采用改进非线性CS扰动方程补偿了随方位偏移量线性变化的调频率误差.仿真结果表明,改进算法的大斜视角大场景成像性能优于传统的高分辨大斜视角成像算法.     

风场的科学计算可视化在导弹射击中的应用

在导弹射击时,消除风会对导弹飞行造成不利的影响,因此基于可视化分析的研究模型、流程等,利用科学计算方法直观分析优点对风的大小和方向进行分析,并采用开放图形接口对实验风场数据进行了三维图形绘制以提高导弹打击目标的精度,对实际中导弹的风场阻力研究有一定的指导意义.
