This paper describes a multi-channel S-band radar receive system designed as a laboratory testbed system for studying wideband radar array signal processing. The receive array was designed using a combination of low-cost commercialof-the-shelf components and a custom-designed surface-mount printed circuit board assembly. It has been tested using LFM-CW waveforms with a center frequency of 2.4 GHz and a bandwidth of 600 MHz. By using components manufactured to operate in the "Wi-Fi" wireless communications band, the cost of the system has been minimized. This paper presents the design of the system, test results, and some sample ARD surfaces from the system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
