Abstract

ABSTRACT
Passive surveillance system (PSS) is one of the basic equipment in process of the electronic
reconnaissance. During the past ten years multilateration PSS have been engaged in air traffic
control too. Well-know systems in this field are e.g. TAMARA and VERA-E which are
products of the Czech Republic industry. 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 reconnaissance information. The paper fixates to problems of recent PSS
systems range increase independently of signal sources parameters. The possibility of range
increasing looks through the receiver bandwidth adaptation. Receiver bandwidth adaptation of
the PSS system provides increasing of the receiver sensitivity and result is the increase of the
range. Theoretical analysis of the energetic conditions is present and some results of the
modeling and simulations shown in paper.
