10.1.2. General Concepts
The Target Injection is based on a rather simple principle of generating an echo of precalculated power after
a given delay (determined from the target range).
The azimuth at which the echo is generated is also pre-determined from the scenario, but is recalculated
towards the expected interrogation number.
For that purpose, it is important that this target generator can accurately determine the IPR (interrogations
per revolutions) of the radar and that this IPR remains stable over time.
The generated target power is precalculated for every azimuth and as such for every interrogation. The
power basically is dependant on the range, plus a number of extra programmable parameters.
