Re: R-27 AAMHmm, does it mean that both seeker and proximity fuse are measuring doppler of the target? Why would the Tchaika proximity fuse need the information about the target approach rate before launch?. When activated (after launch 2-24sec) it works in centimeter wave band comparing of transmitted/received signal, so it is doing the doppler itself. The time after launch prior to proximity fuse activation depends on target type and target distance/aspect. The RGS is tuned on the litera(frequency) of the KNP transmitter. You are saying something different that it is tuned on the velocity of target (returned cw frenquency, which varies due to doppler.?????)At last I agree with that, the LOCK-ON is achieved after launch for the RGS and before launch for TGS. That`s exactly what the source is saying.
