Most successful naval SAM?

This won't solve problem of receiver burning out due to overload.

You're Russian, you should be used to overengineering things so that doesn't happen.

Can't say, out only ramjet SAM - the "Krug" - was command-guided)

Speaking as Former Radar...

You going to need alot of power to burnout a half decent receiver.

The Talos system was decently over built cause it was a gen 1 with all that implies.

By the time burnout happens from reflection?

You looking at the last... bout 50 meters depending on the distance from the Targeting emitter.

This also of course depends on the Emitter output power and 8 other factors like angle of reflection. Couple of which you can tune to avoid it, even automatically with 60 tech.

Well, the AN/SPG-49 illuminator for RIM-8 Talos have a pulse power of 5 megawatt (for search/track) and continius power of 5 kilowatt (for illumination).

The Type 909 illuminator for Sea Dart, if I rrecall correctly, have a peak power in low megawatts and illumination power of 1.5 kilowatt.

Er, isn't 2K12 "Kub" (SA-6 to NATO) also ramjet powered? And guided by semi-active radar homing?

The AN/SPG-49 illuminator radar was so powerful that the Moon was regularly used as a calibration target also during project Apollo when Apollo missions were flying to the Moon the Talos missile-cruisers were firmly instructed to NOT use the Moon as a calibration target during the duration of each mission.

Yup! The SA-6 Gainful does use a SARH seeker and is ramjet powered.

Yes, but it have different configuration, with air intakes mid-hull:



So there is a lof ot space for seeker in missile bow. And there is no need to use inteferometer, since gimballed dish could be easily installed.

If I recall correctly, the reason for such excessive power was that initially Talos was supposed to use pulse-based guidance, and overpowered pulses were the only way for missile seeker to detect anything?

Without going into every detail, ever hear of a "surge protector?"

The reason for the size of the target tracking radar on the ship was to get one with 1950's technology that had an accurate enough beam at 75 miles to guide the missile close enough to ensure a kill with a conventional warhead. Technology to do that at the time was very bulky.

 

[Dilandu]

If it was that simple, missiles weren't forced to turn their seeker off near the target. The surge protector would basically break the missile homing each time it hit by a stronger-than-expected signal.

Okay, about seekers:

The interferometer antenna configuration has two characteristics that must be under-
stood. First, the body fixed nonsteerable configuration requires a total field-of-view consis-
tent with the maximum required look angle. Second, the gain associated with such an anten-
na is considerably below, the gain available with a steerable antenna. A complete com-
parison of these body-fixed antenna characteristics with steerable antenna characteristics is
quite complex, and the results depend heavily on the geometry assumed for the encounter.

From "MISSILE GUIDANCE: INTERFEROMETER HOMING USING BODY-FIXED ANTENNAS", by J. F. GULICK and J. S. MILLER, John Hopkin's University APL, 1982.

So it's exactly as I stated; the inteferometer seeker is, by definition, low-gain and require much more powerful signal to work.
