Abstract:

This report introduces the Advanced Radar Waveform Generator Two-Channel Upgrade (ARWG-2). The ARWG-2 is implemented in the commercial AMD-Xilinx Gen3 RF system-on-chip in the ZCU208 Evaluation Board form factor. It provides a flexible platform for generating user-defined radar pulses with complex features such as intrapulse modulations, near real-time custom waveform generation, pulse-to-pulse frequency agility, user-defined amplitude, frequency and phase modulation, and composite pulse group generation. It includes multiple user interfaces including serial command line interface and Python-based graphical user interface. The ARWG is connected to a supporting PC via a Gigabit Ethernet interface and can therefore interact with powerful applications residing in PCs or across networks. This upgrade increases the capacity of the generator from its previous single-channel design to a two-channel design.
