You see, in English language basically everything that can't run away and hide up on a tree on its own is considered female.
And this thing is even flying towards us, which qualifies double, especially for slashdotters.
Nothing with mass can ever reach c.
Easy solution. Just prepare a spaceship with a catwalk, and use some of the already anorexic wannabe fashion models as astronauts, promising them they'll get themselves as cover on Vanity (or whatever).
By the time they are nearing C, their mass will be zero.
If their second "click" is used as a reference signal, i.e., the signal itself, not its echo, it could be used not only to invert the first signal and filter out the noise, but also give information about the distance:
Depending on when the reflected echo comes in - delayed (and overlaid) - to the reference (second) signal it would also account for the distance of the target.
Quoting an absolute meaningless part of TFA doesn't help either.
The radar "sends out two pulses in quick succession to cancel out background noise", like dolphins which "send out two pulses in quick succession to cancel out background noise".
I also think that sending out two pulses in quick succession may cancel out background noise.

And as "everything used to be better in the past", that's nothing new, just browse some writings of Roman authors. But then, even nostalgia isn't what it used to be.
Everything was better in the past, even the future!
