现代导弹防御雷达中有复杂的数据处理系统,这种系统对实时处理能力有严格的要求。为满足这些系统的最大处理要求,可将搜索、跟踪等功能分配给单独的互连计算机。然而,由于复杂的相互制约,很难预测所推荐的分布式系统事 实上能否满足各项指标。MULTISIM计算机程序可以模拟用于雷达数据处理的多计算机系统,因此可以帮助预测系统性能。这种模拟程序可以模拟包括中央处理机、通信总线、共用存贮器和雷达回波的各种分布式计算机系统。还可以模拟硬件连接和软件之间的相互关系。对一分布式计算机系统实例的分析表明了雷达回波处理时间、实际部件的利用率和总吞吐量等结果在帮助评价推荐的设计方案中所起的作用。
Modern missile defense radars have sophisticated data processing systems that have strict requirements on real-time processing capabilities. In order to meet the maximum processing requirements of these systems, functions such as search, tracking and the like can be assigned to separate interconnected computers. However, due to the complicated mutual constraints, it is difficult to predict whether the proposed distributed system can satisfy the various indicators in fact. MULTISIM computer programs simulate multi-computer systems for radar data processing and can therefore help predict system performance. This simulation program simulates a variety of distributed computer systems including CPUs, communication buses, shared memories and radar echoes. You can also simulate the hardware connection and software interrelationships. Analysis of an instance of a distributed computer system shows the effects of radar echo processing time, actual component utilization, and total throughput on helping to evaluate the recommended design.
