Radar Field Analyser - RFA641 Edition Date: 28-Feb-18
Range Performance Analysis" by Lamont V.Blake. This calculation uses elevation, frequency and
range to determine the lens effect on the radar signal. The calculation is performed based on the
graphical interpretation of the curves presented in the reference, and therefore it has a limited
accuracy of 0.1 dB.
10.3.5. Determining the Effect of Parameters
The effect of each of these parameters can be verified using the educational simulator in the lower half of the
tool. All the calculated values and the parameter values are shown in that display and are recalculated each
time you change the Range and Altitude of the simulated target.
Beware: Only the Range and Altitude can be modified in this window. All others are indicators of
calculated or parameter values.
Change the range or altitude using the sliders or simply by selecting a target in the list.
In case a swirling case is selected, a recalculation (using the Recalculate RCS button) generates a new
random RCS and as such also modifies the target return power and the RFA output power.
Make sure you “booted” the RFA641 and the dial is rotating. If the dial fails to rotate, make sure you
properly connected the trigger signal and the ARP signal.
10.3.6. Compilation of Scenario
Compile the scenario using the Compile button, the following window will appear:
