The 'it' meaning the Brahmos? That is a claim difficult to prove.
An 'interception' is essentially an interference of a travel on a path. So from this perspective, a tail chase is technically an interception. But in order for a tail chase to have any chance of success, the interceptor's speed should be at least 3 times
THE POSSIBLE MAXIMUM SPEED OF THE TARGET. Against aircrafts, of which whose designs usually limited to Mach 2 or rarer Mach 3, the interceptor can be Mach 5 or 6 and this is sufficient. Against the SR-71? That is for another discussion.
If the target is known to be capable of speed faster than the interceptor, then the best tactical deployment against this target is head-on and here lies a different can of worms. If the Brahmos is approaching at Mach 10, for example, I could put up a cricket ball in its path and the collision will be enough to bring it down. The problem with this head-on interception scheme is that I have only one chance to bring that cricket ball precisely in the Brahmos's path. I could put up a large brick wall as well.
The problem with a head-on interception is precisely because of that one chance. If the interceptor missile failed, it must attempt to reacquire. It must turn around and that require time and fuel. Its sensor, radar and/or infrared, usually have limited field of view so if its turning radius is large and time consuming, its odds of re-acquisition will not be favorable. If the background is filled with clutter, as in Earth terrain because the target is low flying, odds of re-acquisition is reduced further.
Because the interceptor have only that one chance for a head-on intercept, its sensor and guidance package must be the focus of discussion. What kind of sensor? What kind of flight control guidance laws? What kind of flight control mechanism? Of course, the answers to these questions will
NOT be revealed in details but the general principles of them are public enough. Sensor would most likely be active radar. Flight control laws would most likely be proportional navigation. Flight control mechanisms would most likely be deflector fins for aerodynamic exploitation or even in combination with deflecting thrust mechanism.
We have to examine the interceptor in as much details as we can gather in the public realm and the best we can do is make odds on its success. But if your friends are willing to divulge classified technical details here...
We chinese are looking forward to encounter this missle and have some turkey shoot 
to have balls remember...u r a dark skin Endian...
