近幾年，微波遙感的運(yùn)用越來越廣泛，并根據(jù)應(yīng)用范圍的不同，對信號源的要求也各
有不同，尤其是信號的波形、工作頻率和帶寬等參數(shù)，更是對探測效果起著關(guān)鍵作用。本文介紹一個任意波形信號發(fā)生器系統(tǒng)的硬件設(shè)計(jì)和實(shí)現(xiàn)，重點(diǎn)介紹了主控器和混頻器等關(guān)鍵電路的設(shè)計(jì)。

Abstract: Recently, the microwave remote sensing technology is combined with the life
characteristic. It creates new fields in the heart detection area. For different applications, different requirements are set for the Radar source, especially the waveform, working frequency and bandwidth, has big influence on the detecting result. It introduces the hardware design and implementation of the signal generator system which is suitable for the microwave remote radar, mostly introduces the master controller and mixer circuit design.
