The Long Wavelength Demonstrator Array (LWDA), located in New Mexico near the center of the VLA, provides a test facility for the Long Wavelength Array. Consisting of 16 dual-polarization dipoles, and associated direct sample digitizing receive chains, the array operates between 60-80 MHz and is capable of operating in both beamforming and all-sky monitoring modes.The LWDA has been operating since late October, 2006. In order to test the capabilities of the LWDA, we have collected several data sets in which 1-bit data was simultaneously collected from all antennas for post-processing. These data sets enable event searches in post-processing, which allows us to test software for future real-time processing. In this presentation, we will focus primarily on describing the characterization of data sets collected during the November, 2006 Leonid meteor and the August 2007 Perseid meteor shower,during which time the array was configured to detect signals scattered from meteor trails. We will compare these results to similar results taken from periods not associated with specific meteor showers.
