Application and analysis of FRI (Finite Rate of Innovation) Super-resolution technique in navigation system

Abstract

Recently, as positioning information becomes very important, various navigation systems are rapidly developed and consequentially improving the position accuracy becomes the purpose of these researches. In this respect, in the field of signal processing, as part of improvement of the navigation system accuracy, the researches for the application of Super-Resolution techniques at navigation system have been carried out for advanced navigation system that is possible to obtain much higher accurate positioning information than conventional navigation system’s positioning information. As a result, a number of researchers have developed various types of Super-Resolution techniques and, recently, new Super-Resolution technique called FRI (Finite Rate of Innovation) which can extract data much more efficiently than conventional sampling technique for a particular signal is developed. For this reason, in this research, FRI technique is applied to Radar system and vision system that satisfy the FRI signal environment and feasibility of proposed techniques is evaluated with simulation results.
