微波大功率发射机的长脉冲设计

Long-pulse Design of Microwave High Power Transmitter

随着武器试验突防手段的技术发展,对靶场应用的测控雷达提出了新需求,希望增加发射脉宽,提高发射平均功率,增加发射带宽,满足对目标多维特征的测量。对接发展新需求,结合研制实践,介绍了一种车载式C波段多注速调管发射机,其特点是脉冲宽度宽、输出功率高、发射带宽大、可靠性高,在平原及高原条件下可机动工作。对发射机的设计思想和系统组成作了阐述,并通过与以往同等功率量级的发射机设计方法的比较,从长脉冲全固态调制器设计、高稳定度高压电源设计、高原适应性设计等方面重点讨论了研制中的设计思路和实现效果。

With the development of penetration technology in weapon test,new expectations are put forward for TT&C radar.Wider pulse width,higher average power and larger bandwidth are required to be used for the multi-dimensional measurement of targets.To meet these requirements,combined with the practice,a C-band long-pulse multi-beam klystron transmitter is introduced.It is a vehicle borne transmitter.The transmitter has the characteristics of long pulse width,high output power,wide bandwidth and high mobility.It can work stably under various environmental conditions of plain and plateau.The design scheme and system composition are described in this paper.By comparing with the previous transmitter at the same power level,the implementation effects are given.The highlights are focused on designing of long-pulse all-solid-state modulator,high stability HVPS and plateau adaptive realizing.
