Ramjet is not impressive, it is a fast missile but I doubt Pakistan's ships radars will have a problem intercepting them. Streaker just means a fast missile that flies high unlike Harpoon, or Exocet which fly low, and slow(er). Pakistani ships equipped with HQ-16 will have no problem engaging the missiles, if ECM don't work.
Excerpt from Quora
"This means that in the end, BrahMos is a “streaker” type high speed heavy antiship missile just like all of its Soviet predecessors, and that is the exact threat type that the United States Navy’s air defense doctrine is built to counter."
