Description

<p style="margin-left:0in; margin-right:0in">This Multiband Software Defined Radio (SDR) sensor system proposal will demonstrate the ability to operate within multiple frequency bands and across multiple technology platforms in a single transceiver.&nbsp; The center frequencies and bandwidths chosen are representative of current demonstrated commercial or research devices and bands used: 400 MHz, 900 MHz, and 2.4 GHz ISM bands, with bandwidths of approximately 10 MHz, 26 MHz, and 100 MHz, respectively.&nbsp; SAW sensor development proposed is for a cryogenic to high temperature sensor, high temperature strain sensor, and magnetic field sensor.&nbsp; Demonstration of other passive technology sensors will also be demonstrated.</p><p style="margin-left:0in; margin-right:0in">This proposal presents a series of technical objectives that will have a significant benefit to a broad range of wireless sensors, and advance the state-of-the-art and capabilities in sensor technology.&nbsp; The effort will demonstrate a multiband software defined radio (SDR) sensor transceiver that can interrogate any passive resonator or delay line technology sensor within a given band.&nbsp; The proposed sensor systems will lead to improved safety, reduced test, and space flight costs by providing real-time analysis of data, information, and knowledge through meshed wireless networking.</p><p style="margin-left:0in; margin-right:0in">The SDR system approach has the following advantages and advancements:</p><ul><li>Switchable bands</li><li>Software defined center frequency and bandwidth</li><li>Low cost configurability</li><li>Easy and fast programmability of SDR and post processing</li><li>Works with any passive sensor within the given RF band, temperature, strain, gas, magnetic field and others</li><li>Maximize signal-to-noise ratio for a given sensor type, i.e., resonator, delay line, CDMA, OFC, etc. by minimal hardware changes</li><li>Software for parameter extraction of multiple measurands</li><li>Simultaneous interrogation of all in-band sensors</li><li>Multiband-switchable system: contiguously measure sensors across frequency bands</li><li>Wireless network connectivity for information and data logging from multiple sites and sensors</li> </ul><p style="margin-left:0in; margin-right:0in">&nbsp;</p>
