RCS OF Different Fighters

Regarding thermal imaging and heat emission,

If the aerial target is located at an angle close (in line) to the sun. Can the heat from the sun cause interference if there is no filtering?

Also, can sun be used a cover (from thermal image) if sun is behind the inbound aircraft ?

Heat IS NOT the same as infrared. Heat is the source of infrared, but the two are not the same.

Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared. Even objects that we think of as being very cold, such as an ice cube, emit infrared. When an object is not quite hot enough to radiate visible light, it will emit most of its energy in the infrared. For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits.

In regard to your question, it is better rephrased with the word 'infrared' because that is the sensor type -- infrared sensor. So yes, infrared radiation from the sun have seduced heat or infrared seeking missiles before in the early days of the technology.

Air Force Magazine - reputed and credible source - recently disclosed that F-35A Block 3f (current baseline production model) have uniform RCS of a bee [3.8 mm]. This translate to Russian S-400 system being able to notice this bird at around 21 miles mark from its position. This is noticeably lower than all estimates in the public domain.

Doesn't that mean the F-35 should be able to engage first?

Indeed, friend.

Does this mean the F-22 has an RCS of a mosquito? lol

A fly actually...

Depends what kind of fly. Some flies are the size of a house. Some flies are smaller than a poppy seed.

house fly*

F-22 has smaller RCS than house fly. More like RCS of fruit fly.

Whats the RCS of the J-20? 1m2

 

[Yongpeng Sun-Tastaufen]

Whats the RCS of the J-20? 1m2

J-20 RCS is equal to watermelon seed.

 

[LeGenD]

Does this mean the F-22 has an RCS of a mosquito? lol

Close to 1.0 mm.

 

[Yongpeng Sun-Tastaufen]

All these RCS are theoretical. There is no reliable way to calculate RCS. It depends on weather condition, radar, angle etc.
