雷达

This thesis is focused on the study of 12-channel intermediate frequency sampling digital receiver array for one radar system.

本文以某雷达接收机为应用背景，开展了十二通道数字中频接收机阵列的研制工作。

The intermediate frequency circuit of LFMCW radar was designed, including signal processing circuit and the data sample system.

然后对LFMCW雷达中频电路进行了初步设计，包括信号预处理、数据采集电路。

Intermediate frequency linear frequency modulated signal has been widely used in radar,for it has precise measurement on target's speed and distance.

中文摘要： LFM信号是目前雷达中应用的主要信号形式，它具有很高的速度和距离分辨率。

The key of this technology is to use the intermediate frequency signal digitization and the I/Q demodulation in the radar and the communications domain as well as the digital signal processing technology.

技术的关键是采用雷达、通信领域中的中频信号的数字化和I/Q复解调及数字信号处理技术，从而大大地降低了成本、提高了系统的稳定性、灵活性和一致性。
