Global demand for radar systems is growing rapidly, with the market expected to reach US$46.8 billion by 2030. The growth rate is 4.5% per year. Angular coordinates are key parameters for accurately determining the location of the signal source. System analysis of current super-resolution angular position determination algorithms, such as MUSIC, ROOT MUSIC, MVDR and ESPRIT, helps establish relationships between radar system performance and application requirements. The choice between algorithms depends on the specific application requirements, operating environment, available resources, and other factors. The article provides a comprehensive analysis of these methods with an emphasis on their performance characteristics in various conditions. The dependence of the choice of algorithm on specific operating conditions, navigation requirements and resource limitations highlights the importance of a systematic approach to optimizing the direction finding process. At high interference levels, MVDR and ROOT-MUSIC demonstrate better reliability, while in less demanding conditions MUSIC remains preferred due to its efficiency and ease of implementation.
