Abstract : Modeling RADAR signals in software allows the testing of potential electronic counter measures and electronic counter counter measures without the associated RADAR hardware and test facilities. Performing a characterization process on a real world RADAR system reveals all imperfections within the system. The Lab-Volt (TM) RADAR system served as the characterized real world RADAR system. The characterization process consisted of measurements at selected front panel locations on the Lab-Volt (TM) transmitter module, antenna pedestal, receiver module, and dual channel sampler module. Due to the overwhelming influence of antenna parameters on a received signal, the characterization process also attempted to derive an antenna transfer function that described how the antenna filters a signal that is passed through it. The characterization process also determined the manner in which different adjustments influenced the signal. A MatLab simulation modeled the Lab-Volt (TM) system operating under ideal conditions. Comparing measurements from the characterization process and the MatLab simulation placed numerical values on the imperfections in the Lab-Volt (TM) system. Finally, integration of the Lab-Volt (TM) system explored an elementary hardware-in-the-loop configuration.
