Not realistic !!!!!
You are constantly forgetting about the beam width.
Under your conditions for the x-band, the beam width is 0.3 degrees. It takes 34,000 steps to scan a 60 * 60 sector. Modern radars scan this sector in about 10 s with a range of 150 km on average. The full view for the APG-81 is 19 seconds at a distance of 160 km. This is approximately 0.02 seconds per step. 34,000 * 0.02 = 654 s or 10 minutes.
Yes, but I would not like to be the operator of such a radar station, in a combat situation, which scans the 60 * 60 sector in 10 minutes.

These are the recommendations of the ITU. The International Telecommunication Union (ITU) is the United Nations specialized agency for information and communication technologies – ICTs.

I hope you won't argue with ITU.
I suggest you stop. And they will return to the conversation when there are figures from official sources.
This is a monograph by an Air Force major who refers to some other writer. I never found the original source. But the author writes everything about everything.

Also, are you not confused by the B-2 figure? In all sources that give a low RCS level - This figure is much less.
Here is an interview with Zelko in 2009.

Yes, I admit that he could be wrong, but by + -10 degrees.
Otherwise, he would simply say that the rocket came from the right.
But there are no peaks in the 40-60 sector either.
