摘要
讨论了一种工作在s波段长波部分的大功率宽带发射机(PTX)。本文主要关注主要PTX特性由于PTX,操作在线性调频脉冲模式下有几个独特的特点:高脉冲(800千瓦)和平均(12千瓦)在一个非常宽的频带(10%)具有高频谱纯度(相对幅度相位噪声谱密度低于-100 dB / Hz承运人在100赫兹,信号频谱中的常规组件的相对水平低于-70分贝)。考虑了雷达系统大功率宽带发射机设计的几个重要方面，特别是多波束速调管的优点。
A high-power broadband transmitter (PTX) operating at the longer-wave part of the S-band is discussed. In the present paper principal attention is paid to the main PTX peculiarities due to which the PTX, operating in the LFM pulse mode has several unique features: high pulse (up to 800 kW) and average (up to 12 kW) power in an extremely wide (10%) frequency band with a high spectrum purity (the relative spectral density of amplitude-phase noise is below -100 dB/Hz at 100 Hz off the carrier, the relative level of regular components in the signal spectrum is below -70 dB). Several aspects, vital for the design of high-power broadband transmitters for radar systems, in particular the advantages of multiple-beam klystrons, are considered.
