Russian Black Eagle Surpasses America's Abrams

I should draw it to you

I wouldn't say that RPG is a relic. But that's an offtopic.
So let's settle this: you want something completely self-made or on the basis of some existing weapon?
And can you find me a name of program that can define target by shape (so I could prove to you, that this kind of program are not suited for our seeking duty )

Lol! Alex Ivanov, you must have been living under a rock! Technology advences from day to day. I wouldn't imagine anyone trying to mount a workstation on rocket! There are much smoother alternatives..

Don't you think a computing power of 400 Mhz and 128Mb Ram that fits inside your palm would be enough? And wait a couple of years and even more powerfull small scale devices will be available.

And remember, the missile will only be fully active for a very short time, or it will be set to "idle" to just do the occasional scan. Thus it requires only a small battery and no cooler is needed at all.

Because this seeker would be made up of commercially available parts and many of them mass produced, it would be very cheap.

400 MHz can be not enough. It depends on quality/resolution of video and precision of analysis. If you want to recognize color, shape, determine speed of objectfrom a video your camera gives you, and do it in real time with minimum of errors, 400MHz can be not enough. BTW, Intel compatible processors and their mehaherzs aren't a worth example. Pentium 150MHz isn't enough even to decode mp3 without delays (though it isn't just proc's fault).

About couple of years - I meant your idea isn't implementable today. I'm sure that after couple of years it will be implementable technically.

Scandinavian, have you ever developped any microcontroller-based device? Do you know what "image recognition" means mathimatically? Do you know what image recognition from video means mathimatically? Do you know any method of recognition? (I'm just wondering)

Well, I really don't know whats involved in decoding an mp3, but I suppose the compression algorithms are extensive so it's no surprise it takes a long time. This has nothing to do with image recognition however.

Yes. I've worked with displays, input devices and electric engines connected to a microcontroller. It's not as complicated as it sounds.

Personnally I have only experience in 3D programming. I'm not interested in image recognition but I'm pretty sure most programmers would be able to take on the effort (including myself). As I said, it has been done many times berfore and there is software available for it today.

The biggest challenge is actually testing the missile and make it so that it has a stable and controlled flight, for example it must not rotate in it's flight. But this only needs to be done once. When the build instructions are made public anyone can build it without the need to test or adjust it further.

I'm glad we both have at least some expirience in this field. Otherwise our discussion would be funny.

Just one example - recognition of a text (known set of images) from still picture takes relatively long time (it is not instant). Recognition of object without having full info about it from video will take MUCH more time, believe me.

Hi.

Soviet(Russian) armour was better than western till 1960's then West cought up and in 70's surpassed Soviet armour.

The result can be seen now. 80% of tanks deployed by Russia in Grozny was destroyed. 5 tanks (Abrams) were destroyed till now in Iraq (mostly just "mobility kill" by Iraqis, and then totally destroyed by US forces to prevent capture by OpFor-Iraqis).

As for the RPG-7. It's good against APC's and T's but unreliable against modern Western tanks (and ERA equipped T's).
Most T's are now being fitted with ERA (Explosive Reactive Armour), that can protect them from single warhead RPG's. However new type of ammo ("top attack") makes ERA obsolete, since ERA cannot be fitted on the top of the tank turrent.

The best tank in the world is Israel's Merkava Mk. 4. Then Abrams, Leo 2, Leclerc, ...

ERA is basic configuration for soviet and russian tanks from the moment of invention - 1983. In first chechen campaign, because they were not fitted with ERA.( why - it's another question.)
In second chechen campaing russia didn't lose not one single tank.

5 tanks (Abrams) were destroyed till now in Iraq (mostly just "mobility kill" by Iraqis, and then totally destroyed by US forces to prevent capture by OpFor-Iraqis).

Scale of city battle is incomparable.

It's reliable. Most of Abrams were destroyed by RPG. BTW.See page N 3 of the current thread for new rounds for it.

Really?

Merkava is very good tank, probably the best. But T can stand in one row with the others.

P.S Russian systems of active defence such as Arena and Drozd are highly capable to protect tanks. What analogues can west offer?
