abstract = {With the technology advance in analog-to-digital converter (ADC) and digital-to-analog converter (DAC) devices, associated with high speed digital signal processing (DSP) using field-programmable gate arrays (FPGA), modern Electronic Warfare Receiver (EWR) systems design have moved toward digital implementation applying software-defined radio (SDR). In this context, Model Based Design (MBD) emerges as a development methodology to integrate high-level system simulation, automatic hardware description generation, and hardware-in-the-loop (HIL) testing. This paper proposes a concept demonstration of the MBD methodology applied to an Electronic Warfare (EW) radio frequency (RF) recorder triggered by pulse envelope. MATLAB/Simulink models are initially used to simulate the system at a high level. Subsequently, the Xilinx System Generator tool generates and transfers the hardware description to a Xilinx FPGA. Finally, the hardware implementation is validated using HIL technique. Comparative measures between the simulation-only and hardware-in-the-loop versions are presented.},

abstract = {A new architecture for malicious jammer mitigation in GPS signals is proposed. The technique employs a smart antenna array followed by a signal-to-noise ratio (SNR) in discriminator. The architecture provides good results jamming scenarios in which a malicious jammer runs at exact GPS frequency and carries a data stream spread by a valid Gold code. Here, direction of arrival (DOA) estimation is provided by a high resolution eigenstructure and a null steering beamforming beacons a null towards the malicious jammer source. A post-beamforming SNR discriminator, fed by the resultant array output signal, discards ones whose SNR after despread process overcomes a determined theoretical threshold, ensuring additional interference suppression. The results show the efficiency of the proposed methodology in terms of probability of tracking error in function of the DOA displacement between the malicious jammer and the GPS desired signal.},
