Is this a joke? China using military radar technology to wage war on mosquitoes

[HariPrasad]

May be an extension of 4 pest xampaign. IIhope that result will not be the sames

Real question is what do you do once you find the mosquitoes. Not like they've got micro missiles for gunning them down.

Same radar could be equipped with powerful microwave emitters to fry them or possibly laser unit with that radar.

This is going to piss off the Chinese on this forum but there is nothing spectacular about this. In fact, on this forum yrs ago, I explained how radars have been used to track insects.

Insects, birds, leaves, and assorted weather phenomena are called 'volumetric targets' by radars.

Just in case anyone thinks I made up the phrase 'volumetric targets'...

...calculation of polarized scattering from volumetric target...

In radar detection, a volumetric target is a target that is composed of many discrete parts, in other words, a target that is NON-UNITARY or not necessarily of a solid nature.

When many birds are in close proximity to each other, reflecting radar signals among the individual birds create a single radar reflection. If one bird leave the flock, the reflection signal is a bit weaker, and so on. Eventually, if the flock is thin enough, even though we can visually see a grouping of birds, the radar will see nothing. That is the nature of a 'volumetric target'.

Same with leaves on trees, grass, rain, fog, and insects. All are volumetric targets.

Mosquitos are no different. There are plenty of youtube videos of mosquito swarms.

To distinguish out an individual mosquito is not that difficult, after all, for yrs some specifically designed radars can distinguish out individual rain drops.

...radar’s unique high-resolution waveforms, which allow the bulk and individual hydrometeor properties to be inferred at the same time.

The word 'hydrometeor' is a technical word for certain weather related items.

So distinguish out individual mosquitos, we use high frequencies, very short pulses, and a large array. In radar detection, there is an inverse relationship between array size and beamwidth.

http://code7700.com/radar_beam_width.htm

The larger the plate antenna on your radar the narrower the beam...

For any given freq, the larger the array, the smaller the beam. Conversely, the smaller the array, the larger the beamwidth.

To distinguish out individual mosquitos, the operating freq should be in the millimetric (mm) bands because the mosquito is only a few mm in size. The beamwidth should be a small as possible so that would require an array size of meters across. But because of the short pulses, this would mean very short distances so just because the mosquito is more difficult to detect than an F-22, the mosquito radar would be useless against the F-22. These are the laws of physics that not even China can defy.

The radar is for detecting mosquitos only; therefore it is not intended for detecting "F-22". duh

Duh...

"Yi, who has knowledge of the radar but is not involved in the project, said mosquitoes would be more difficult to detect than a stealth aircraft like the F-22, which has a special coating and geometric design to avoid showing up on radar screens."

The insinuation is clear...Duh...Duh...Duh...

You are so smart! Give me a high 5! That idiot Yi should be fired and you should be the one designing the radar since you clearly have the more knowledge about radar than a scientist in one of the most prestigious design bureaus in China! From what you have written, I can say with 10000000000000000000% certainty that you are at the forefront of every field in science. There is simply no way to detect two objects of similar RCS; If two things have the same size under a radar, then you can't detect one of them!!!!!

I did say it would piss you guys off. My technical posts usually do.

release the engineered mosquitoes to kill the population of the mosquitoes in detected area.

China and fake news and lies.

One thing India and China have in common.
