摘要

本文简要介绍了基于辐射信号空间、幅值、相位、频率相互一致控制的多位置辐射源系统电磁辐射聚焦方法,以及由于信号和天线参数的各种随机波动对其潜力的限制。对多位置辐射系统中频率分布为v型的天线、控制系统的电气参数和设计参数的不同随机和确定性变化对聚焦脉冲峰值功率水平、持续时间和重复周期的影响进行了统计研究。空间-幅-相-频控制律的参数在形成单个时空脉冲和在这组时空脉冲中形成一系列时空脉冲时,必须在等于发射器输出端的脉冲平均持续时间内保持稳定。考虑了信号空相频控制律参数的精度和稳定性要求。分析了多位置发射机信道中发射信号空时脉冲序列形成过程中各种参数偏离给定值对发射信号空相频控制规律的影响。结果表明,在辐射方向上,发射器相位中心位置误差的影响并不取决于到焦点的距离,但影响很大,需要采取特殊措施加以减小。

Estimation of requirements to signal parameters at V-shaped frequency distribution in mathematical model of multi-position transmitter system
This paper is a brief review of methods for electromagnetic radiation focusing using a multi-position system of radiators based on mutually consistent spatial-amplitude-phase-frequency control of radiated signals and limitations of their potentialities arising from various random fluctuations of signals and antenna parameters. The statistical study of influence of different random and deterministic variations of electrical and design parameters of the antennas, control systems of the radiated signals with V-shaped frequency distribution over the aperture of a multi-position radiating system on the peak power level, duration and repetition period of the focused pulses is carried out. The parameters of the space-amplitude-phase-frequency control law must be stable for a time equal to the average duration of the pulses at the output of the emitters when forming a single space-time pulse, and when forming a sequence of space-time pulses during this pack of space-time pulses. The requirements concerning accuracy and stability of parameters of the signals’ space-phase-frequency control law are considered. The analysis of the influence of various kinds of deviations from the given values of the parameters of the space-phase-frequency control law of emitted signals in the channels of a multi-position system of emitters during formation of space-time pulses sequences is carried out. It is shown that the influence of errors in the location of the phase centers of the emitters in the direction of radiation does not depend on the distance to the focusing point, but is significant and special measures are required to reduce them.
