need evidence Silkworm radar - HARM does not see in TOO

[Gierasimov]

Hi

Is this working as expected? Can you not engage Silkworm radar with TOO mode.

Shows as U on the EW format and can be engaged in SP mode. Does not show in TOO HARM format though.

Seems there was a report last year but no input from ED on this.

Checking into it. Thanks.

Is there any evidence of the use of HARM on surveillance radars of anti-ship systems in reality?

VVS used an ARH to target a chechen insurgent leader using a satcom phone. I don’t see the reason of a more programable seeker head like the one installed in an 88C couldn’t be adapted for an environment that required so (heavy numbers of coastal batteries of Silkworms in the Iranian coast).

Interesting concept

Thanks Chizh,

This is the answer I needed. It does make sense as those radars would not paint the aircraft, I was assuming a bit, in lack of public documentation, that what you see on EW format would be what you get in TOO mode.

I guess I don't know enough about how this weapon operates.

 

If I ever find the aforementioned evidence you will be the first to know.

Yeah the HARM is both a programmable seeker and can home in on radio/radar emissions. Maybe it'd show up as a U (for unknown) but there is no reason it can't see the radar emissions from the site.

Chiz, it should be able to still track the radar simply by locking onto the U rather then the S/etc during the handoff phase of the missile programming. The HARMS meant to be able to track what the RWS can detect

 

The AGM-88A HARM entered service in 1983 and constituted a major improvement over the earlier missiles. The weapon used a broadband spiral antenna, a software programmable seeker which was conceptually similar in design to an RWR, providing coverage from the C through to the J band (2-20 GHz). The missile used a steel cube blast fragmentation warhead, and a low smoke rocket motor. It was faster and longer ranging than the Shrike and Standard

 

The receiver employs Crystal Video Receiver (CVR) and Superheterodyne techniques, subject to frequency band. Reports indicate that the receiver processor is capable of sorting threat pulse trains in high density environments, from the C through to the J bands (0.5-20 GHz). The C-model HARM receiver has superior sensitivity and pulse de-interleaving performance over previous models, and is thus able to discriminate individual emitters in higher threat density environments, at greater ranges, compared to previous models.

 

Because the missile is field reprogrammable, the missile can be programmed to engage not only the standard threat radars in its internal software library, but also arbitrary emitters such as ATC Primary and Secondary radars or weather radars.

What comes for today, is there a RWR code for Sworm sites radr?

If you have unclassified public evidence it is possible please DM me.
