Cutting-edge Israeli radar wins air force approval for Tejas fighter

[Maarkhoor]

Tejas always reminds me a good song of Raj Kapoor "Mera Jota hai Japan, Meri patloon englistani, Sar pe laal topi russi phir bhi dill hey Hindustani".

How about Gripen ??

Does it remind u of any good hindi song ?

Or JFT for that matter with russian engine ?

 

[knight11]

May be A2A scan mode with SAR scan

I very much doubt Jags will be used in such roles after the advent of strike fighters like Su 30 and Rafales!!And besides,AESA radars are extremely power hungry,and I don't think that Jag's power-plants can cater for that need.

This will be interesting Aesa for Terrain avoidance, terrain hugging, Scanning Ground target, narrow beam A2A scan.

AESA radars are extremely power hungry Brother can you shed some light.

My Question is that when they already developed according to Indian members Utam AESA radar why they go for Israeli Radar is Utam another failure like Tejas if so then why they always brag about under developed weapons and systems

Mr. Troll You already claiming Tejas as failure, Uttam is indegenious effort and all information is available in open domain.

And before copy pasting the articles pls read what you are posting, its AESA Radar for AEW or AWAAC not the nose mounted MMR like Uttam.

Suppose one TRM gives a moderate (a very very moderate by the way) signal power output of 10 watts and multiply that number by 800 (potential total number of TRMs) and you will get what I'm trying to convey here.Although,while looking at that earlier comment,I think I might have blown it a bit out of proportions.

How dare u question his copy pasting talent

another indigenous acquisition- the word "indigenous" changes its meaning completely when used by indians- -

Fist thing first .. Author : Ajai Shukla
Good news: EL/M 2052
Very Good news: EL/M 2052 Upgrade Joint development
Confusing news: Capability to field EL/M 2052 in Jags and Mirages.. Size and power.. Will there be a limitation say 80% capability vs say LCAs in terms of radar? Don know

Now,
Operate on: 3 to 10 Kilovolt Amperes depending on antenna size (thats why Mirage and Jags may get this upgrade)
Radar Weight: Around 80-180 kg depending upon the antenna size
Antenna size: Adapted to aircraft nose limitations
Note: We donknw how much capability reduced if antenna size and power is less as i said in confusing news

- 1500 + T/R modules as per Israeli forums.
- ridiculously high tracking capability of 64 targets
- In air-to-sea mode, it can acquire and track surface targets up to 160 Nm away implying 296 km (again in Israeli forums)

According to flight global article of 2005, it ststaes
"Elta Systems is to launch flight trials of its prototype EL/M-2052 fire control radar using Israel Aircraft Industries' Boeing 737 testbed. Initially intended for integration with fighters like Dassault's Mirage 2000 and Sukhoi's Su-30, the system can simultaneously detect 64 airborne targets and has high-resolution synthetic-aperture radar and ground moving target indication modes for air-to-surface operations, says Elta."
Radar trial


Perhaps this indicate there wont be any loss of efficiency for Mirages as it was intended for them too.. Then Jags can handle too (i assume) without drop in performance.

10 watts or 10killo volt ampere, Sir its the output power of the whole Radar.
first thing first as brother @PARIKRAMA have shown that the antenna is different to adapt the nose size, so no. of T/R modules will vary. Second the problem of AESA is not the power consuption but the heat dissipation.
The more power consumption you are pointing is in some Radar Mode Condition.
Due to the behaviour of microwave transistor amplifiers, the power efficiency of a TR module transmitter is typically less than 45%. As a result, an AESA will dissipate a lot of heat which must be extracted to prevent the transmitter chips becoming molten pools of Gallium Arsenide - reliability of GaAs MMIC chips improves the cooler they are run. Traditional air cooling used in most established avionic hardware is ill suited to the high packaging density of an AESA, as a result of which modern AESAs are liquid cooled.

AESA provides much better beam agility, much lower power requirements, vastly superior reliability and fault tolerance, low probability of intercept due to frequency agility and lower output power requirements, and far superior sensitivity and detection range relative to output power. Due to their sensitivity, AESA radars can be used as passive sensors.

No 10 watts can not be the power output of the whole radar!!There are reports that latest GaN Transmitters can provide upwards 50 watts of signal strength!!The rest of your comment is on target though.

@Omega007 thanks for the thanks -- Love you Prasun da

Dude!!Are you in any way mistaking me for Prasun??!!

No I thought you are the one who he taking all my post dictating Prasun. Yes I am very much influenced with Prasun, but I don't follow him blindly.
