The probability of detecting and tracking RADAR targets in clutter at low grazing angles

posted on 2018-05-11, 11:58 authored by Ronald W. HaddowModern military acquisition and tracking RADARs are required to operate
against aircraft and missiles specifically designed to have minimal
radar cross section (RCS) and which fly at very low level to take
maximum advantage of terrain screening.
A model for predicting system performance is necessary for a range of
terrain types in varying precipitation and seasonal cultural conditions.
While the main degradation is from surface clutter and denial of sightline
due to terrain and other local obstructions, several other factors such
as multipath propagation, deliberate jamming and even operator performance
contribute to the total model. The possibility that some radars may
track obscured targets, however briefly, by using the diffraction path,
is of particular interest.
Although this report critically examines each of the contributory factors
in order to select optimum values for inclusion in an overall computer
prediction model; a new surface clutter model is specifically developed
for sloped terrain using actual clutter measurements. The model is
validated by comparison with an extensive survey of worldwide clutter
results from both published and unpublished sources.
Certain constraints have been necessary to restrict the study to a
manageable size, while meeting the requirements of the sponsors.
Attention is therefore focussed upon performance prediction for
typical mobile tracking radar systems designed for operation against
small RCS low level targets flying overland.
