By the way found something interesting , regarding Akash sam , it kind of verifies my earlier hypothesis.....
it seems the RF seeker will work in conjunction with the command guided module.
When the Akash is launched initially it will be command guided and if conditions permit , Akash will enter end game manuvers with command guidence only.
Again depending on real time operational requirements if the Rajendra radar is painted by airborne jammers/ECMs/fired on by ARMs etc , the radar will switch off just before command guidance inputs positions the missile within the zone where the onboard RF seeker can be activated to begin search for the target in its periphery.
Again even if the missile is not withen the optimal zone where the RF seeker can search and acquire the target and the Rajendra radar is forced to switch off, the onboard memory module preserves the previous command guidance inputs etc and algorithms calculates the trajectory based on them which will guide the missile close to the target where the RF seeker can be switched on to search and lock on its targets.
So basically we have 2 guidence modes for akash. One must realise onboard seeker must be within a predesignated distance from the target before it can successfully search locate and lock on its target.
Rough analogue will be mid course guidance which must be provided first to take the missile close to the target so that the onboard seeker can come into play.
Here command guidance comes into play both as the mid course guidance as well as for end game guidance, with the added benefit that the onboard RF seeker takes over the end game guidence if the command guidance is terminated after mid course guidance phase (even earlier but with drop in kill probability) due to adverse conditions or enemy countermeasures.
Nice touch I must add to increase the potency of Akash sam manifolds, really complicates things for enemy aircrafts.
Am really looking forward to Akash mk2 capabilities.
And if that's not enough it seems portable decoy emitters matching the frequency of the radars are positioned to seduce ARMs.
Also many don't know that Akash sam is certified and tested to defeat PGMs. During tests it defeated Israeli PGMs.
