#2 is this just the SS-nx-26 Yakhont thingy they joint developed?
as in supersonic bad if it gets in your way but spoofable and avoidable even if fast?

#3 Yakhont based.

The Indian contribution was the targeting computer, guidance system and software.

The Indian DRDO made the thing much smarter.

The seeker relies on airborne radar platforms like Ka-31 helicopter. The target coordinates are inserted in missile memory immediately before launch and during the cruise phase the missile steers itself via Inertial platform with autopilot. At pre determined distance from target Brahmos switches on its active radar seeker to detect target. In case os of sea skimming profile missile starts radar search and achieve lock-on upon "popping up" from under the radar range which is about 25 km's.

In the lo/hi/lo profile it performs a first short radar search at a range of 50 km to verify target position and then reverts to inertial navigation in radar silence for the descent phase to sea skimming attack run before switching the radar on again at closer range.

There is no provision of in-flight data updates via data link from launch or airborne platform. Its estimated that Brahmos can perform both active or passive homing modes. passive modes like anti-radiation or home-on-jam.

Supersonic speed in cruise phase will ensure ships will not be able to move much farther away from the estimated position. As a result the missile will be able to start active radar search closer to target on a narrower sector of 40-45 degree. Hence the targets ESM detection and countermeasure will have just 3.3 seconds to react.

The seeker uses a hybrid form of pulse compression, in which bursts of short pulses are phase-coded so that they can be compressed; the bursts can also be Furier-transformed to discriminate chaff clouds. This particular pulse compression technique was adopted to hold down peak power, so making ESM detection difficult. The missile can also scan a number of targets in the area to identify the one it is supposed to hit. This capability is normally obtained through screen matching criteria, but Brahmos employs special algorithm that classifies targets based on their radar cross section as contained in the pre launch data.

On shore attack mode the seeker can detect large structures or DRDO has developed navigation and flight control computers to guide missile to precision impact against fixed targets (capability already tested).

#4 Thanks john.
Your ref is indians defence ministry so i'll have fun qualifing it open source.
