相控阵雷达的研制包括两个方面:一、雷达硬设备,其中包括天线阵面、接收系统、发射系统以及信号处理等等;二、计算机的软件设计。如果没有一个先进的控制方案就不能充分地显示出相控阵雷达的先进性、灵活性。下面两篇文章就是讨论有关多目标跟踪的软件设计问题。 跟踪多目标的问题,不只是研究跟踪算法,还要考虑一些其它问题,如:提出跟踪报告、目标的相关判别、目标的分类、多目标跟踪中的轨迹发生交会时的处理,以及目标的合并、退出跟踪等等。诸如此类问题都应在软件的设计中体现出来,并提出相应的处理办法,只有这样才能适应复杂的目标环境的变化。 另外,随着跟踪的目标数目的增多,对控制计算机的容量和速度的要求也就会愈来愈高。如果目标数超过了计算机的设计容量将造成系统饱和使之不能工作。一种解决的办法是无限制地提高计算机的速度和容量,这在系统设计上容易做到,但是很不合算。最好是在软件设计上想办法。本期发表的《在密集目标环境中用相控阵天线进行计算机控制跟踪》和《用一部相控阵雷达同时跟踪多个目标》两篇文章提出了用队形跟踪法来处理这一问题。所谓队形跟踪法是以质心跟踪控制和边缘跟踪控制为基础的。当目标比较密集时,跟踪这一队形的质心,并同时能得到队形各个成员的轨迹。这种设?
The development of phased array radar includes two aspects: First, the radar hard equipment, including antenna array, receiving system, transmitting system and signal processing, etc .; Second, the computer software design. Without an advanced control scheme can not fully demonstrate the advanced phased array radar, flexibility. The following two articles discuss the design of software for multi-target tracking. Tracking multi-objective problems involves not only tracking algorithms, but also other issues such as tracking reports, criteria related to targets, classification of targets, processing of trajectories in multi-target tracking, and the merging of targets , Exit tracking and more. Such issues should be reflected in the software design, and put forward the corresponding approach, the only way to adapt to complex changes in the target environment. In addition, as the number of targets being tracked increases, so does the need to control the capacity and speed of the computer. If the target number exceeds the design capacity of the computer will cause the system to become saturated so that it can not work. One solution is to increase the speed and capacity of the computer without any hassle, which is easy to do in system design, but not cost-effective. It is best to find a solution in the software design. Two articles, “Computer Controlled Tracking with Phased Array Antenna in Intensive Targets,” and “Tracking Multiple Targets with a Phased Array Radar at the Same Time,” are published in this issue. Using the formation tracking method to deal with this issue . The so-called formation tracking method is based on the tracking control and edge tracking control. When the target is relatively intensive, tracking the formation of the mass center, and at the same time be able to get the trajectory of each member of the formation. This set?
