It is not necessary to use either tan or cosine. It is best to convert the degrees to radians and then simply multiply 5000 kms by the radians. The accuracy of the missile can then be estimated as follows:



(0.001/3)*(1/57)*5000*1000 which is 30 meters.

(.001 / (3 x 180)) x (22 / 7) x 1 000 x 1 000 = 5.82010582 meters by using the radians calculation. It still does not hint at ASAT capability. DRDO was clear that this gave us ASAT. Later interviews suggest the difference between the ASAT capability and what's available now is a 600km range radar which is being upgraded to 1400 km range.



So the question remains on the quoted number. The Chinese ASAT hit a satellite which had dimensions of 1.4m diameter x 1.8m height. Which of these calculations is the right one?



(.0001 / (3 x 180)) x (22 / 7) x 1 000 x 1 000 = 0.582010582 meters which is more than enough to give us ASAT capability.

Thanks.



Added later:

Assuming we have BMD capability at 600km also requires a better accuracy than reported.



(0.00001/6)*(1/57)*600*1000 = 0.0175438596m

Given the missiles are tracked at 0.1 cross section as quoted in reports.



If we have BMD, we also have ASAT. If we have ASAT our CEP is in single digits. It's possibly the signal being sent out. I am not sure I can separate DDM from the facts. I also don't know what DDM expands to but I understand this is what we call DDM. I normally am kush with the Arun analysis, I just wanted to explore a bit more.
