Problem statement. Trends in the development of existing communication and data transmission systems are largely based on the use of ultra-wideband signals that can operate in the complex interference environment. At the same time, due to the wide range of tools that work based on the use of such signals, algorithms for detecting signals against the background of noise and interference of various types are studied not sufficiently. 

Purpose. To study the effect of various types of interference on the efficiency of ultra-wideband quasi-radio signal detectors.  Results. Synthesis and analysis of algorithms for detecting ultra-wideband quasi-radio signals against the background of Gaussian white noise and signal-like interference in conditions of various a priori uncertainty was performed. A comparative analysis of the resistance to interfering signals of various detector circuits was performed. An assessment of the reduced efficiency of detectors under the influence of various types of interference was carried out. The dependences of detection characteristics on various parameters of interfering signals were obtained and the parameters that make the most destructive impact were determined. 

Practical significance. Recommendations for improving the efficiency of detectors operating in the complex interference environment were formulated.
