Performance Characteristics of Radar
Location and Radio Navigation Systems
Radar location and radio navigation systems specification can be divided into tactical,
technical and operational. This chapter will examine more precisely tactical characteristics since they at the most degree define a purpose and capabilities of practical
use of radar location and radio navigation systems.
5.1 Operational Range of Radar Location and Radio
Navigation Systems
Operational range of radar location and radio navigation systems is determined by
a target detection range (aerial vehicle, maritime vessel or other object). Target
detection range means a greatest distance D max , by which a decision on the presence
of a target in conditions of specified probabilities, correct solution and false alarm
is made. Here we should pay attention that in language for general purposes the
detection range means a “maximum distance” at which a target can be detected. At
such definition, a maximum range—is some fixed value (e.g., 50 km), above which a
target is impossible to detect (e.g., 51 km). Further, throughout a material discussion,
a probabilistic nature of the most generally accepted definitions will be underlined.
Any object, falling in radar coverage zone, is inside a radio beam of some limited
time. Let a total energy, radiated by a radar in all directions in a time of one target
illumination, be a value E . At uniform distribution of this energy in space around
a radar, an energy flux density near a target, positioned at D distance, comprises a
value:
t =
E
4π D 2 .
