An indoor S-band radar receive array testbed

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 commercial-of-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.
