Long range missiles for PAK FA to feature AESA seeker heads

[Arzamas 16]

Design Bureau "Detail" Corporation "Tactical Missiles" will develop an advanced system for homing missiles K-77m air-to-air, which is equipped with a promising aviation complex tactical aircraft (PAK FA).

To do this, the company will take a massive retooling. Create a pilot production plant is going in 2015. About it, "Izvestia" reported chief engineer Mikhail Vershinin.

Despite advances in technology and a steady decline in the cost of production, phased array as an element locator remain expensive, which casts doubt on the expediency of their single-use rockets. Nevertheless, such a missile hit the plane enemy will pay many times and production, and possible damage, the deputy director of the Institute of Military and Political Analysis Alexander Hramchihin.

Obtain an advanced targeting system, missile K-77m air-to-air will keep the target and adjust to its maneuvers.

Homing missiles will ensure the aircraft or missile hit the enemy with the first run. The new radar will provide instant response to a sudden maneuver missile targets, and increase compatibility with digital systems, fifth generation fighter aircraft. Such an element radar is usually installed on the aircraft, including the T-50, and air defense systems.

According to general director of holding "Roselektronika" state corporation "Rosteh" Andrei Zverev, Russia has a chance to become one of the first countries to adopt the new technology necessary to create high-precision missiles.

"Digital active phased arrays while promising direction and are not currently commercially available, either in Russia or abroad. Certainly, accuracy, agility missiles will increase, because the digital array has more speed and less energy compared to analog, - said Andrei Zverev .

According to the plans UPKB "Detail" to launch production will not begin until February 2015 - this date must be prepared working documents for the implementation of technology.

Haters talk, Russia walks

Range?? Must be around 150km+ or so.

 

[[Bregs]]

Russia is rocking on with variety of new weapons

So this means that ECM will be almost useless against this missile ???

No, that depends upon the robustness of the jammer in question and well the brute force at its disposal. The Americans will find a way through it, the French have invested heavily and come quite close to perhaps the most perfect on board EW system already...for every better bullet someone will come up with a better armor.

The best defense any radar system, from the classical concave to the planar to the AESA, have against countermeasures is as a narrow beam as possible. Of course, with the older designs, sidelobes are more vulnerable to countermeasures than with the new, but attacks against sidelobes are for a different issue. Anyway...It is the main lobe, or beam, that transmit and receive that give us 'radar detection', and AESA produces the best main beam in terms of beamwidth and beam quality.

Now...The most important thing in terms of producing a beam is the relationship between the operating freq and array size/dimension. It is an inverse relationship: The smaller the array, the larger the beam.

One of the key constraints was that of beamwidth, and the basic rule which applies is that for a given radar wavelength (frequency), the wider the antenna or antenna array, the tighter (narrower) the beam.

The larger the beamwidth, the higher the vulnerability to main lobe countermeasure attacks and the greater the need for things like freq agility or pulse characteristic variability...

...To confuse the countermeasures.

The above example is just a small sample of pulse characteristic generation. The sophisticated and 'classified' pulse forms have literally tens and even hundreds of thousands of variations in a few seconds, depending on the operating freq. The smaller the system, like in a missile, the greater the difficulty in generating sophisticated pulse form to resist countermeasures. At this point, it depends on the base technology foundation of the country that produces the missile and this is where the US have traditionally been ahead of Soviet/Russia and continues to this day.

An array and an element are the same thing ????

@Dillinger

Many "elements" come together to form an array.

True.

A single transmit/receive (T/R) unit is an element and many T/R units combined makes up an array. Another thing to understand is that an antenna is not necessary the same as an array. With the classical concave dish or the newer planar antenna, there is no array to speak of. But with the advent of T/R elements in the ESA design, the antenna is the physical structure that contains or holds the array.

Good development

 

[HariPrasad]

We should start work on L band seeker very long rage missile.
