Im sure the sa-7 are in reserve as of today since they have made strides in the misagh and the new qaeem

[Im sure the sa-7 are in reserve as of today since they have made strides in the misagh and the new qaeem]

1) misagh, qaeem are Pakistan build sa-7.

what does that meant pakistan sa-7

Indeed I believe Iran did R&D the SA-7 back in the day but the system is very obolete today...a simple flare system can defeat the system not to mention its a 42year old system

yea is it misagh-3 in works or just some honest mistake
i dont recomand paying for that report after that mistake do you guys

Details

what is that is it igla

I have an idea about making next generation misagh-3, misagh-4 or what ever you want to call it!

It is obvious that misagh-3  can be fooled by any aircraft equipped with fairly simple flare lunching system.

With current advances in CCD and optic technology a simple regulator can be added to this weapon that works in the following way.

System is locked on hot spot of the airplane. A separate simple optical system is digitally zoomed on the aircraft in a way that half of the sensors on the  CCD are covered by the airplane.

When one or several flares are lunched by the  airplane, the moment the missile change its direction towards the flares, picture of the aircraft on CCD will go to one of the edges of CCD. If this happens for a few milliseconds the infrared guidance will be shut off and the missile will be adjusted in a way that the airplane shadow moves to the center of CCD.

When the picture of the airplane is somewhat centered on CCD,  the infrared guidance will be activated again.

Each time a few flare is lunched the same will happen and misagh-4 can discard the flares one after one.

In worst case scenarios with continuous flares, the infrared guidance could be switched off and on with a frequency suitable to defeat the purpose of the flares.

The implementation of this system and the steering system could be very easy with a low resolution CCD with 200x300 resolution. At lunch time and about 5,000 m from the target this system should provide with a picture of the plane at about 20x30 pixel. When picture of the target reached more than 100x150 pixel, the digital zoom should jump 2X.

The steering of the missile should be based on the infrared unless the picture of the plane starts to move rapidly to the edges of CCD. At this moment the infrared steering should be disabled and the visual steering should be connected, trying to center the picture.

Since the Aircraft should be visible by eye at the launch time we can assume it will be visible during the the whole process. The aircraft shades might change if it is viewed against the sun or in front of the sun. It is simple logic to separate it from the background light in any condition. The modern CCD are very sensitive and I think it might operate with infrared lights too and it should be possible to detect the airplane even inside the clouds and during the night time.

The commercial digital cameras are good enough and the whole optical equipment should be less that 50 Gr. The software for steering based on data from the CCD is very simple and could be implemented by any undergraduate in Sharif university computer science or electrical engineering. If implemented as microcode or Assembly language, it is maybe one or two cheap for the logic and memory less than 5 gram.

I do not know about mechanical steering of misagh-3 but since the missile is fairly simple it should not be a problem to make modification so it should be controlled by this new feature.

I think when we put somebody's life in danger and equip him with a missile he should have at least a fair chance to hit his target.

In case of misagh-3 I think we have to do some modification to it in order to increase its deterrence. 

 

Since we do not need a high resolution picture a hole with 2 mm diameter will be enough. The lens can be slightly bigger than that and cover the hole. If you need the center area of the head cover to be gray you can make tiny area of 2X4 mm oval shape at the perimeter clear plastic and the isolate it so the light goes through the lens behind it and do not disturb the infrared sensor. Remember If there is a will there is a way!  The electronics for miniature CCD cameras are widely available to be used in cell phones. Once you have the picture on the CCD of 1-10M pixel then you can look at appropriate area in the CCD for steering.  some of the better cameras even have logic for anti shaking in video application. A lot is already is done in commercial applications and can be imported even under sanction.

I suggest to gut out a missile and put it one the desk of some engineers from Sharif, define the problems and space requirement. These people are smart they find a way to squeeze  about 50 gram somewhere!
Restriction imposed:
1. Total Weight restriction.
2. Total Space restriction
3. Using current steering
4. Trying to integrate the new steering logic in the current steering hardware and software. 
5. In case of the optical system failure the system should behave as a missile without this system.
6. Modification to the system should not change current system functionalities.

Since we want to use the existing steering system we need only electronics and a miniature optic and CCD and these things can be as small as you wish!

The main problem will be how to merge these two logic and if it is possible to add the code in the existing hardware/software on the missile.

I would do it this way:

a latch with 5 digit of data is produced by the new equipment (optic + simple embedded software).

digit one: the picture is at the center or not.
digit 2-5: go up, down, left, right relative to the rocket.

The existing missile software should be modified like this:

It should be able to read this external 5 digit code.
if the digit 1 is is off (picture of the airplane is at center) do nothing and execute existing missile guidance.
if the digit 1 is on then let the digit 2-5 steer the rocket for a few millisecond. At any moment if the digit one turned off the steering should go back to the infrared guidance.

they should some of these to the mujaheddin in iraq and afghanistan and some to hezbollah and hamas

nice but that is a MANPADS doing in police exhibition??

by the way it does not look like Misagh-1 nor 2.
isn't it a newer virsion?

It looks like a Misagh

I thought the front is not similar by checking some unclear pictures
your right my mistake.
