BA Pass is a better expert at this than engineers who build the radars. Didn't you know?

bhaai yeh sb pappu asslickers hain

they dont see anything other than pappu family asses and boots

i knew in 2 days they ll arrange ppl to somehow prove it , Abhi 2din baad scientist bhi aake verify karenge. 

 

Wah modi gi Wah

 

:aha:

ft ke haath me aa gai asslicker

u should prove the report is misleading with reasoning

otherwise continue asslicking.

Radar technology specialists have said that surveillance radar signals can easily pass through clouds, contesting Prime Minister Narendra Modi’s suggestion that clouds could have helped shield Indian Air Force aircraft from Pakistani radars during the Balakot airstrikes.

A senior air traffic control officer and two other specialists familiar with surveillance radar capabilities said clouds are largely transparent to the typical wavelengths at which radars intended for surveillance operate. Two of the three experts requested not to be named in this news report.

“Radars detect objects on the basis of echoes or signals that bounce off the objects — clouds do not usually impact such echoes or return signals,” said Shriram Vasudev, assistant professor at the school of engineering, Amrita Visva Vidyapeetham, Coimbatore.

The European Space Agency’s “edutool”, an online learning and training tool for secondary school students and teachers, says: “Radar signal easily penetrates clouds so that images can be acquired regardless of current weather conditions.”

The page also says: “Optical images contrast with radar in that they do not work at night and cannot see through clouds.”

A senior scientist familiar with surveillance and weather radars said some radars might be specially tailored to detect water vapour or clouds. “But radar signal passes through the clouds. For example, we can ‘see’ right through a cyclone,” the scientist said.

An air traffic controller said some clouds might cause clutter, or unwanted noise, which — for civilian aircraft surveillance — is overcome through a secondary surveillance radar that uses signals beamed by transponders aboard civilian aircraft.

In a secret mission, onboard transponders are likely to be turned off and detection will have to be based entirely on primary surveillance. But even in the presence of cloud-induced clutter, the controller said, the signals do pass through the clouds.

Three other air traffic control officers, who deal with communication, navigation and the surveillance of aircraft, said cloud cover or rain cannot prevent detection of any flying object by a primary radar.

“Surveillance of aircraft is done with the help of primary and secondary radars. A secondary radar cannot detect an aircraft if its transponder is in the off mode. But a primary radar doesn’t depend on the aircraft’s transponder. It detects any flying object within its range,” an official said.

The primary radar system transmits electromagnetic waves and analyses the waves reflected back by the object.

“The primary radar sends out the waves and its receiver receives the waves sent back. The object can be static like a tall building or moving like an aircraft,” said another official. “Even a thick cloud cover cannot prevent the signals from being transmitted.”

However, the primary radar also receives waves from the clouds. “The two waves simultaneously received from clouds and the aircraft can clutter the signal. But through technology, the signals from the clouds can be suppressed by the ATC and only the image of the aircraft can then be seen,” another official said.

Statement: “I am not a person who knows (defence) science. I thought there are so many clouds and it’s raining, so there’s a benefit for us. We could be protected against radar. Everyone was in a dilemma about what to do. Then ultimately, I said we have cloud cover, so let’s go.”

Who said it: Prime Minister Narendra Modi to News Nation.

Accuracy meter: 0/5

As both the lay person as well as experts have noted on social media, cloud cover offering protection against military radar is false. Radar, which stands for Radio Detection And Ranging, works by transmitting radio waves. Different kinds of radar work at different frequencies, depending on what their targets are. Unlike light, however, radio waves pass through objects, depending on their frequency.

Apart from the military, radar finds use in other scientific and common applications. Geology employs radar, which directs radio waves into the ground and helps geologists study the composition of the earth. They are effective at measuring rock porosity as well.

Weather radar, meanwhile, functions at frequencies where clouds actually stop the waves. The water vapour droplets reflect radio waves back, so the clouds can be detected and modelled through the Doppler Effect. Some even measure the intensity of rain.

Radar used by military and air-traffic controllers, however, are built to detect solid objects and purposefully penetrate clouds. The frequencies at which they function make weather transparent and help detect aircraft through all kinds of weather. This is why special anti-radar aircraft are designed carefully to have edges that deflect radio waves and their composition is such that they could potentially absorb a fair amount to make them invisible to radar. Except for these specialised vehicles, there is no escaping radar in the air.

While PM Modi did say he doesn’t understand the science and that cloud cover preventing detection by radar was his initial thought, he fails to clarify the statement further. He proceeds with his narration, claiming they decided to launch the attack because of and under cloud cover (the implication being that it offers protection from radar). Thus, his statement is 100 per cent inaccurate and is scientific misinformation coming from the highest office in the land.

Grow a pair Ankit. This is really an established fact. There are umpteen papers on this subject. 

 

I can understand you taking issue on why PM tried to take credit for this. But surely you so called seculars can find something more substantial to pin him.

To go after PM u need a pair of Balls

I urge my friends to stop giving legitimacy to pidi voices. Let them whine about radars, the only thing that matters is mission accomplished in Balakot. Never deviate from objectives achieved, all this background noise can take nothing away from the decisive decision making of our PM. What use is high level education and IQ/knowledge when you lack balls and/or are skeptical of your own armed forces a la MMS?

 

Enjoy life and chillax, knowing that PakMil and their jihadi rats will always sleep with one eye open as long as we are led by Modi. Even a mention of his name makes their body hair stand, check Pak social media (esp of ISI/PakMil/PTI)....how much they hate him and how desperate they are too see a non-BJP govt in Centre. When the thoughts of our bitterest enemy find resonance with a section of our countrymen you must realize they don't have the best interests of India in their hearts, so stop indulging them and let them choke in their own bile.
