This article reviews the commonly used methods for expression of radar's ECCM performance, points out their disadvantages and proposes that it is required to establish the formulae which consist only of the radar's technical parameters in order to measure the radar's ECCM capabilities.By means of logical argumentation and ambiguity function theory we can derive the followings: ( 1 ) The radar's 4-dimensional generalized resolution parameter can be used to express the radar's basis anti-clutter capability. The simplified expression of this parameter is T0 (the dwelling time at a radar's target, or the integration time of a echo signal of the radar) × Bs (the radar signal bandwidth) X G (the radar antenna gain); ( 2 ) The product of an average radar's transmitting power and its generalized resolution parameter PT0×BsG can be used to express the radar's anti-jamming capability, and the same formula may also be used to express the total interference rejection capability in gross.By another approach, I. e. by calculation of the radar's output signal to interference power ratio under various interference conditions, the given formulae have further been proven. The given formulae consisting of the radar's fundamental parameters are the fundamental parts of the measuring formula of the radar's ECCM capabilities. They represent the radar basic or potential ECCM performance. The supplementary factors for the ECCM capability formulae are composed of the technical specifications of the radar's ECCM devices. The general rule of com-position is to take the typical quality level (or the middle level) specification (in db) as the base figure. If the quality level of some devices is higher,a positive factor will be got, and if lower-a negative. For example, theequation for MTI supplementary factor ρM isρM(db) = SCV-25(db) where 25 db is the middle level specification for SCV of modern MTI radar.As many radar systems consist of multiple channels, in this article we propose a set of equations for the multichannel radar system's ECCM capabilities in terms of the ECCM capabilities of the individual channel.In the last part of this article, 4 radar systems are taken as examples, their ECCM capabilities are calculated by means of the given formulae. Application of obtained results to radar's system analysis and system design are discussed.

本文论述了度量雷达抗干扰能力的方法,提出了一组通用的度量公式。这些公式的基本部分是由雷达的主要技术参数组成。代表雷达的潜在抗干扰能力。公式的补充部分是由雷达各种抗干扰技术措施的指标所组成,代表这些抗干扰措施的质量水平。用这组公式可以计算出雷达抗消极干扰能力、抗积极干扰能力与综合抗干扰能力的表征数值。本文给出了计算举例,讨论了计算结果在雷达系统分析与总体设计中的应用。

This paper gives an idea how to judge the antijamming of a radioproximity fuze by means of the quantitative characteristics of jammingwhen the efficiency of the weapon system obviously decreases to a definitevalue in fulfiling tasks. For the active jamming, the qualitative charac-teristies are represented by its radiation power, and for the passive jamm-ing, they are represented by the mean desity of the volume of the chaffcloud. In this paper, some calculating formulas are derived for thebath cuses.

本文提出,无线电引信的抗干扰准则可以用武器系统完成任务的效率显著下降到某一限定值时,干扰的定量特性来评定。对有源干扰来说用有源干扰的辐射功率,对无源干扰来说用金属偶极子云的平均体密度作为抗干扰准则的定量特性。对这两种情况,分别推导出计算公式。

In this paper the performance of the moving target detection of radar(MTD), primarily the equivalence adaptive effect for the rejection of color clutter,such as weather and chaff jamming, is first analyzed. And then the developed MTD whichis formed witli 8 points FFT and has a group of band filters is introduced. Finallyvarious experimental pictures taken in the laboratory and at radar station are atta-ched.

本文首先对雷达的动目标检测器(MTD)的性能(主要对抑制气象杂波、箔片干扰等色杂波具有等效自适应作用)作了分析。其后介绍了所研制的,用8点FFT实现的,具有窄带滤波器组的MTD。最后附有在实验室及雷达站实验效果的各种图片。
