    Sanctions Push Iran into Recession

    Any country going for nuclear weapons after 1970 was sanctioned more or less based on its economy. There is a compromise here. So far, the sanctions has not really hit your country. Your annual oil income is decreased by 40 billion $. You decreased the imports about the same amount. Real...

    Woudl the fall of assad mean a strategic gain of turkey ?

    The best thing Syria can get is a second Iraq. Another more probable case, no matter Assad stays or leaves, will be a second Afghanistan in 90s or second Lebanon in 80s.

    Woudl the fall of assad mean a strategic gain of turkey ?

    My worry is Syria becoming another Afghanistan, when Kurds, Alawites, Christians and Sunnis continue to fight for ever.

    A few questions about turkey

    I have a few questions too, lol: 1. What is Turkey's plan for Mediterranean offshore gas? Is there any possibility to face Israel? 2. What is Turkey's plan for Nargono-Gharabagh? Any practical plan to take it back? 3. Which country is Turkey's Number one enemy?

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    Who was stroking his ego? You questioned my comment in the first place by using blunt words and showed off your knowledge. Anyway, I am glad you had radar/avionic background and that helped a lot in our statements. It is related to your first comment where you claimed that I have said something...

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    You have Googled and provided a basic lecture in this part. Good job, thanks. This (Gel) is for other applications such as medical ultrasound and etc and irrelevant to sonar. By shadow, I mean the shading artifact near rigid objects when an abrupt acoustic impedance shift occurs. A midget sub...

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    The problem in coastal/shallow waters is not salinity or pressure but the acoustic impedance matching artifact that makes a shadow near the rigid object boundaries.

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    Multiple modality tracking (multiple sensor tracking) is a computational technique to register IR, radar/sonar and optic signals to overcome the individual artifacts of each sensor and increase the total accuracy.

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    Hi again Gambit, I am glad you are back. The links you have provided are nice but I think you just Googled them and you have not deeply realized the basic physics underlying the beam forming techniques. My main point in the last post was: 'variable depth sonar' is not one entity. It is...

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    Type A Ko-hyoteki is also about 40-50 tones and very small and it has 2 torpedoes too! Japanese used them to attack Australia and Madagascar! There is enough of space in 150 tonnes to do acoustic/IR insulation as well as installing proper sonars. However, it is not enough to out-maneuver US...

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    I am glad you are familiar with 'variable depth sonar'. There are many other techniques to detect shallow water objects as well. Neither of these methods are as accurate as deep water tracking. Would you please elaborate more about the details of the system you are thinking of, so we can...

    IRAN UNVEILS UNUSUALLY BLUE COLORED SUBMARINE

    Japanese did two mistakes regarding midget subs: 1. They used them in the ocean instead of shallow waters. The best stealth mechanism for a country like Iran is the natural barriers. Sonars don't work good in shallow waters. 2. Japanese were not able or did not make a large enough mini...
