摘要
随机信号雷达是一种以微波噪声源作为其发射信号或信号调制形式的雷达 ,相对于传统的雷达体制 ,随机信号雷达具有许多优良的特性。本文介绍了过去 30多年中随机信号雷达的发展过程 ,对其基本形式和相关法、频谱法、反相关法等实现方法作出了系统的总结。并且对几种典型的随机信号雷达 ,如“随机调频连续波雷达”、“正弦加随机调频连续波雷达”和“随机二相码连续波雷达”的基本结构作了介绍。最后对随机信号雷达的发展作了展望。
One form of random signal radars is a radar whose transmitting signal is a microwave noise source or is modulated by a lower frequency white noise source. Compared with the common radars, random signal radar has some inherent excellent properties. The development of random signal radar over the past 30 years is described in this paper. Conventional methods are summarized, such as correlation, spectrum analysis and anticorrelation. Some typical random signal radar systems are introduced, for example, noise frequency modulation continual wave (CW) radar, sine plus noise frequency modulation CW radar and random binary phase-coded CW radar. Finally, the development prospects of random signal radars are analyzed.
