Abstract
We present an improved method for reconstructing images from projection data gathered using 2.4GHz, IEEE 802.15.4 Direct Sequence Spread Spectrum (DSSS) radio signals. Projection data was gathered using received signal strength indicator (RSSI) data provided by a wireless ZigBee network. Previously the image was reconstructed using the inverse radon transform. We reconstruct the image using a simple algorithm developed for objects with a real index of refraction. This method provides improved image quality.
