Characterization and Validation of the GP-3 Experimental Radar System

<p>The experimental GP-3 radar system was originally designed and built under contract for the Air Force Research Laboratory (AFRL). AFRL sought AFIT's support in characterizing the 'as delivered' performance of the GP-3. This research effort focused exclusively on software modifications and hardware validations related to the GP-3 postprocessing mode. MATLAB� was used for development testing and validation. As modified tested and validated the GP-3's post-processing mode is now fully operational. The GP-3 is capable of transmitting and receiving bandlimited (3.5 MHz) waveforms at X-Band frequencies. As demonstrated the GP-3 post-processing mode uses MATLAB to generate and post-process waveforms. System characterization tests included 1) noise performance 2) frequency response and 3) linearity/gain relationships. System noise performance characterization permitted establishment of the receiver 'noise floor' and enabled determination of achievable SNRs (-22 dB to 44 dB for internal noise only).</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
