Abstract:In ultra-low-power systems, energy eff ciency is an important factor. As a result, these systems require techniques to balance between energy consumption and performance. In order to address that, we develop an optimized energy-aware, cascaded detector system for general-purpose detection application. The developed system solves a modified Neyman-Pearson optimization criterion using a Lagrangian multiplier approach with logarithmic transformation. It then uses this solution to systematically set the optimum operating point of the cascade with the help of the Constant False Alarm Rate (CFAR) method. According to Octave simulation results and experimental results from a real-time system implementation, we confirm that our system can meet the required energy constraint and achieve good performance even in noisy environments.
