It does already. Think of the transmitted RWS HPRF waveform divided in 3 phases. On the first one, the frequency, f_{0}, of each pulse remains constant. On the second phase, the frequency of each pulse is increased slightly every single time, by the end of the phase the each pulse a frequency that is f_{0}+BW_{1}(bandwidth). On the third phase, the frequency can either slightly increase at a different rate or decrease. At the end of the phase, the pulse will have a different frequency. f_{0}+BW_{1}(bandwidth) \pm BW_{2}(bandwidth).
Note that the horizontal axis is time and vertical is frequency.
If we get a return of a target coming towards us, its will have a doppler frequency, The return signal will just move up and down. The difference is just doppler.
If the target is at x range, it means that we will receive the pulses at x amount of time. Look how that at a fixed doppler, the return signal can only move horizontally. Here we see that the phases than have an increase in frequency, the \Delta f between the transmitted and received signal will have an extra change in frequency in addition to the doppler. With a bit of math you can deduce an equation to relate range and that extra change in frequency. Thus you measure range with the frequency modulated phases.
Notice as well how even if the received signal is shifted horizontally, the \Delta f of the first( constant frequency) doesn’t change. Thus you get doppler which is proportional to closure rate.
You will get nowhere
The 5km thing is just the dev stuck up on how the N019(bad radar) works and therefore all radars have the same deficiencies and/or work the same.
For example N001/N019 are only able to lock on targets at 70% of their max detection range.
Previously all radar could lock up at 80% of the max detection range. Because the Mig 29 and SU27 have that, all western radars magically have this deficiency. Example, F15s APG-63 only have a ~10% loss
and tornado F3 for example its 85-90%.
You also see it on low altitude flying, N001/N019 have a serious serious drop in performance when they fly under 3km and are looking at targets below the horizon. Close to a 50% in performance due to poor noise control.
If they were to introduce this what would happen, bingo! Everyone’s radars would be a shitty.
Despite that not being the case. The original F16s APG66 has more range in the shorter range MPRF mode than the N019 in the HPRF( for long range detection) at low altitudes.
It’s a textbook " IF THE GREAT SOVIETS CAN’T, THEREFORE THE WEST CAN’T "
