摘要

Criterra是一个软件套件,可以在几秒/分钟内自动确定安全系统传感器的最佳位置和高度,以及基础设施和响应部队的位置,这些位置基于主要的马赛克、视距、时空、多普勒、传播和其他算法,在tb大小的3D地理空间和对象数据库上执行。输入包括传感器系统、屏障和响应力的规格。Criterra基于一种集成了智能和科学流程的方法,可以快速、自动地确定最佳位置,而不是反复试验。自动计算:1)威胁路径和预测位置;2)考虑到区域使用限制内预测的威胁位置/级别,最小数量最小高度传感器塔、移动传感器和/或无人值守地面传感器和通信中继塔的最佳位置,以满足检测、监视和侦察要求;3)围栏的放置;基础设施和反应部队在有限的条件下以高度的信心完成保护和拦截。结果显示在视觉丰富和地理空间精确的3D地图上,用户可以导航或用于计算模型修改,重新定义约束,以及进一步的分析和规划。标准现在可用于支持陆地和海上边界安全威胁、传感器、基础设施和响应分析以及地理空间规划;机场、港口、军事基地等重要基础设施的物理安全分析和地理空间规划;攻击和灾难准备、恢复和响应计划;以及使用3D地图进行部队管理和协作,并将标准分析结果作为嵌入式任务数据。Criterra执行地理空间分析,以预测特定时间的威胁位置,并为CONOPs和风险分析提供区域使用数据。标准用于需求定义、安装、培训、操作、实验以及测试和评估。Criterra可以支持小型和超大区域以及灾难性事件的分析。准则是一种预先放置移动或固定资源的预测技术;定位和分配急救人员。它支持情景理解、信息管理和3D地理空间精确笔记本电脑显示器上的数据可视化。用户可以使用Criterra进行信息共享、协作决策和集成/互操作决策支持,所有用户都可以在共享的3D地理空间地图上引用和绘制数据。它可以支持大规模杀伤性武器事件后的去污和恢复战略、方法和传感器安置。设施、纪念碑、机场、海港、交通基础设施、陆地和沿海边界以及入境口岸都是可以使用Criterra计算模型和Criterra分析算法来确定最佳位置的领域。如今,标准计算模型和分析算法被用于规划地面监视和通信中继器的最佳位置,以保护关键基础设施、边界和港口。Criterra用于规划人员和设施资产的安全。Criterra数据库由两种类型的数据组成:1)一个区域的1平方米切片(大小仅受存储介质的限制),每个切片包含:纬度、经度、高度/海拔、地形组成、坡度、用途(如威胁、允许安装传感器、道路、资产等),来源于GIS数据(如DEM和DTM)和对象数据(如建筑物、基础设施、车辆等);2)雷达、摄像机、UGS、无线电、响应力和屏障规格。准则算法分析切片并为每个切片添加数据库,a)所有其他切片的视线连接性因素,以及b)所有其他切片的横向能力因素。

Criterra automatic location planning
Criterra is a software suite that automatically determines optimum locations and heights in seconds/minutes for security system sensors, and locations for infrastructure and response forces based on dominant mosaic, line-of-sight, time-and-space, Doppler, propagation and other algorithms, executed on a terabyte size 3D geospatial and object database. Inputs include specifications of sensor systems, barriers, and response forces. Criterra is based on a methodology that integrates intelligence and scientific processes to quickly and automatically determine optimum locations that are NOT trial-and error. Criterra Automatically calculates: 1) threat paths and predicted locations, 2) the optimal locations for the minimum number of minimum height sensor towers, mobile sensors, and/or unattended ground sensors, and communication repeater towers to meet detection, surveillance and reconnaissance requirements considering predicted threat locations/levels within area use constraints, and 3) placements for fences, infrastructure and response forces within constraints to accomplish protection and interception with high degrees of confidence. The results are displayed on a visually rich and geospatially accurate 3D map which the user can navigate or use for computational model modifications, redefinition of constraints, and further analysis and planning. Criterra can be used now to support land and maritime border security threat, sensor, infrastructure, and response analysis and geospatial planning; physical security analysis and geospatial planning for protection of airports, seaports, military bases and other critical infrastructure; attack and disaster preparation, recovery, and response planning; and force management and collaboration using 3D maps with results of Criterra analyses as embedded mission data. Criterra performs geospatial analysis to predict threat location at specific times, and provides area use data for CONOPs and risk analysis.
