Blind range is the term given to ranges where%   targets are not able to be detected by the radar. The reason they%   cannot be detected is because they are either too close or too far away%   from the radar therefore returning RF energy during the window where%   the radar is still transmitting. Range resolution is closely related to%   blind range and is described as the ability of a radar to distinguish%   or resolve two targets that are close together in range. Targets%   separated by the range resolution or greater can be resolved.%   Range Resolution = speed of light * pulse width / 2%   By knowing the range resolution required we can then work out the%   required pulse width by rearranging the above equation.% %   REFERENCES: "Radar Fundamentals", Ian Faulconbridge, Argos Press, 2002% c=3e8;  % Speed of light %now use speed of light functiontau = 2*sep/c;  % range resolution
