本文提到的一些问题都是在实践工作中发生的,问题牵涉到: 一、我们经常把等场强曲线作为雷达威力复盖的基础,这种假设在实际使用中和理论曲线不一致。为此,把雷达方程中这一部分加以修正,由于计算比较繁琐,这里推荐了作图法来作修正比较容易,经过这样修正后,与实际情况比较符合。这种分析方法同样适用于分析动目标显示中的波束调制改善因子。二、早期雷达检测理论工作对目标模型的研究也不全面。Swerling的五种目标形式尽管很有用处,但近似程度不够。在梅尔的工作中,又在马克姆和Swerling的基础上,作了大量图表,并采用了目标的其它模型,如χ~2模型、Rice模型以及对数正态模型。它们更加适用于现代飞行器,特别是导弹、卫星等。也提出各种方法,包括观察次数的确定。作者在60年对观察次数也作了分析。现根据我国实际情况对目标模型及观察次数提出了自己的看法。三、作者对雷达目标的能量管理、发展方向,提出了自己的看法。
Some of the problems mentioned in this article occur during practical work. The problems involved are as follows: First, we often use such a curve as the basis for coverage of radar power. This assumption is inconsistent with the theoretical curve in actual use. To this end, the radar equation to be amended in this part, due to the calculation is more cumbersome, recommended here for mapping method to make it easier to amend, after such correction, in line with the actual situation. This method of analysis is also suitable for analyzing beam modulation improvement factors in moving target display. Second, the early radar detection theory work on the target model is not comprehensive. Although the five forms of Swerling’s goal are useful, the approximation is not enough. In Meyer’s work, he made a large number of charts based on Markham and Swerling, and adopted other models of the target, such as χ ~ 2 model, Rice model and lognormal model. They are more suitable for modern aircraft, especially missiles, satellites and so on. Various methods have also been proposed, including the determination of the number of observations. The author also analyzed the number of observations in 60 years. Now based on the actual situation in our country on the target model and the number of observations put forward their own views. Third, the author puts forward his own views on the energy management and development direction of the radar target.
