Radar waves can pass through many substances (they appear transparent like glass) but are reflected efficiently by metals (which act more like a mirror to radar).
Thus if you want to confuse a radar system you can scatter a mass of thin, light aluminium confetti in the air and this will appear as a fog, hiding the target (your plane) from the enemy. Aluminium is used because it is a light metal that can be made into thin sheets or ribbons (aluminium foil).

What do radar engineers make?
A radar engineer works with radar. They have design, develop, install, and test a radar.
What are the advantages of radar range over radar bearing?
Radar range is the distance of the object from the radar. Radar bearing is the direction of the object in relation to the radar. As radar is primarily used for ranging, the range information may be more important than the bearing.
How do you jam a radar?
We're assuming that the question refers to a speed radar gun, and not to a Doppler weather radar, FAA air-route surveillance radar, or military radar. Get a microwave source that runs on 13 volts and radiates at 10.525 GHz. Connect it to your car's electrical system and mount it behind the front grill. Speed radars will not be able to get a reading from the front, and they'll be effectively jammed. The operator will stop you to see what you've got going. Hopefully, he'll ticket you for interfering with local traffic regulation, and then send your ID to the FCC, who will fine you for operating an unlicensed RF transmitting source. And that's how you do it.
Is fmcw radar a doppler radar?
An FMCW radar may make use of Doppler, but it doesn't necessarily.
Why microwave is not used in radar?
Microwave IS used in RADAR.
Can you use aluminium saucepans for jam?
It is not recommended to use aluminium saucepans for making jam, as the high acidity of fruits can react with aluminium and affect the taste of the jam. It is better to use stainless steel or enamel-coated saucepans for making jam to ensure a safe and flavorful outcome.
In what states are radar jammers legal?
If you are looking to jam the police frequency, you are out of luck in the US. It is illegal to use a radar jammer in all 50 states.
Thin strips of aluminium foil released in the air to obstruct radar detection?
Chaff. It's called chaff.
What advantages do laser guns have over radar guns?
Laser speed guns can target ONE specific vehicle, where radar may read one of several vehicle. Laser is harder to detect in advance, and harder to jam than radar.
Troublemaker invented by the british royal air force?
Are you perhaps asking about chaff, used to jam enemy radar?
What are the uses of the objects that use electricity?
Lighting, heating, transport, tv radio, radar, phones, computers, kettles, irons, hair driers, aluminium smelters.
Why should you not use a aluminium saucepan for stewing rhubarb?
Since Jam making uses natural acids. Metal+Acid ------>salt and hydrogen. Since aluminum is high in the reactivity series it will react with the acid from the fruit quickly forming metal based salts in you jam. A steel pan which is lower in the reactivity series will not produce salt quickly so your jam wont be ruined.
What elements in in aluminium?
Aluminium is actually an element, so the only element in aluminium is aluminium.
What is the element that has protons in the nucleus?
Aluminium. Aluminium. Aluminium.
What is the technical name for Missal attracting flares deployed from fighter aircraft called?
Flares are used against heat-seeking missiles, and chaff ( thin strips of aluminium) are used to distract radar-guided missiles.
What is the element that has 13 protons in the nucleus?
Aluminium. Aluminium. Aluminium.
Strips of aluminium foil to obstruct radar detection?
When we were children (c.1948) my father brought home reels of aluminium tape. We used it as Christmas decorations. He told us that the tape was dropped by a plane prior to a raid over the channel. German radar would then think they had a full scale raid coming over the channel. Once the jerries had launched all their fighters to attack and then returned empty, our planes would fly in to catch them as they refuelled. Another trick was to chaff over the channel at height while our planes flew around at low level so again jerry fooled. It was dropped over the channel so that it fell into the sea so jerry couldn't find out how we fooled them, until some drifted onto the French coast. The tape was stiffer than baking foil and about 1/2" wide. You had to be careful you didn't cut your hands on the edges.
