Let
be the integer that labels a pulse emitted by
radar unit B. If that pulse gets reflected, or partially reflected,
by a scattering event, then let
be the integer which the clock
assigns to the reflected pulse as it enters the radar receiver.
These two integers,
![\begin{displaymath}
(n_1,n_2)~,
\end{displaymath}](img106.png) |
(10) |
generated by this radar ranging process are the radar coordinates of
the scattering event. They assign a unique
spacetime location to the scattering event, namely
as determined by
![\begin{displaymath}
\begin{array}{cc}
T_1-Z_1=t-z&\textrm{(pulse moving to the ...
...\
T_2+Z_2=t+z&\textrm{(pulse moving to the left)}
\end{array}\end{displaymath}](img108.png) |

Here
and
are those two events at radar unit B
which mark the emission and the reception of a pulse at B.
