In some examples, a radar system includes phase-locked loop (PLL) circuitry configured to generate a control voltage signal and processing circuitry configured to generate a reference signal to drive the PLL circuitry to generate the control voltage signal. In some examples, the radar system also ...

This paper introduces a digital transmit/receive module for phased array radars.At first,the core of the digital module is analyzed:such as the theory of the direct digital synthesis (DDS) and digital receiver.Because DDS has the advantages of fine frequency resolution and fast switching speed wh...
function Phased Array Radar (MPAR) program [3] seeks to capitalize on this idea by replacing the current WSR-88D (NEXRAD) weather radars with phased array systems that have much better update rates, the ability to track planes and weather targets simultaneously, and the capability to perf...
Digital Array Radar (DAR) is a fully digitized phased array radar in which digital beam forming technique is used both in receiving and transmitting. Firstly, this paper introduced the typical ar-chitecture of DAR. Then, it analyzed the characteristics of DAR, such as the low demand of ...
