An Advanced Embedded Application for Receiver Processor Unit

摘要

To meet the specific requirements of the users for different platforms like ships, aircrafts, helicopters, ground vehicles and submarines Electronic Warfare (EW) systems are used. The Embedded System will have broadband and narrowband operations to meet the strategic needs of EW systems. Broadband operation is achieved by employing a Wide Open Receiver, which will attain 100% Probability of Intercept (POI), whereas narrowband receiver will help in achieving higher sensitivity and better Range Advantage Factor (RAF) against Low Probability of Intercept (LPI) radars. Our proposed scheme is to develop an advancedEmbedded application for Receiver Processor Unit (RPU) to generate the controls for the Digitally Tuned Oscillator (DTO) and the switches in the Built In Test Equipment (BITE) distribution network based on the BITE Command received from System Controller Display (SCD). The output of the RF Source is fed to the programmable attenuator to adjust the power levels required to check the dynamic range of the receiver. In this paper, the proposed RPU generates the controls for various devices like switch filter bank, homodyne receiver etc. The embedded application is thoroughly tested for its functionality using the given lookup table and the results are found to be satisfactory.
