Operating a microwave oven with the door open and pointed straight up is extremely dangerous and should never be attempted. Microwave ovens are designed to be used with the door securely closed to prevent the escape of microwave radiation. If the oven is operated with the door open, it can pose serious health hazards to anyone in the vicinity.
Microwaves emit non-ionizing electromagnetic radiation, which can cause thermal effects when absorbed by living tissue. When used correctly, microwave ovens are designed to contain this radiation and only allow it to interact with the food inside. However, with the door open, the radiation can leak out and potentially harm people nearby.
Using a microwave oven in this way will not have any effect on anti-radiation missiles or electronic warfare (EW) aircraft. Anti-radiation missiles are designed to home in on the radio frequency emissions from enemy radar systems, and microwave ovens emit microwave radiation, not radar signals. Similarly, EW aircraft are equipped to detect and jam enemy radar signals, not microwave ovens.
In summary, operating a microwave oven with the door open and pointed straight up is not a viable or safe method to spoof anti-radiation missiles or EW aircraft. It is important to use microwave ovens as intended, following all safety guidelines and manufacturer instructions to ensure the well-being of users and prevent potential hazards.
