Optimization of Pulse-Modulated Signal Processing in Passive System

Passive surveillance system (PSS) is one of basic equipment in process of the electronic intelligence (ELINT). During the past ten years multilateration PSS have been engaged in air traffic control too. Absence of the signal transmitting and receiving of the signal source only is one of their main advantages. Important parameters of PSS are range and quality of the signal analysis (Vosecky and Juranek, 1989). The possibility of PSS range increasing by receiver bandwidth optimization is the topic of paper. Theoretical analysis of energetic conditions and some problems of pulse-modulated signal analysis are presented. Results of modeling and simulations show in the paper too.
