How does stealth technology works in Fighter jets? and my radar is not able to track the planes in this ? also how does chaff works? to avoid radar detection?
The stelath solutions are meithod of redusing so-called RCS (Radar Cross- Section), and particularly the RCS correponding to reflection back in the direction of the illuminating radar ( Most of the radars are monostatic as opposed to bistatic where illuminator and receiver in different locations). The RCS is effective area of radar energy reflected, either overall or in particular direction (differential RCS). The classical method is by absorbing electromagnetic wave with minimal reflection via gradual ( as compared to the radar wavelength) introduction of dissipative material.

Stealth technology, also known as low observable technology, is used in fighter jets to make them less visible to radar. The basic principle behind stealth technology is to reduce the aircraft's radar cross-section (RCS), which is the measure of how detectable an object is by radar.
There are several ways in which stealth technology works in fighter jets:
Shape: The shape of the aircraft is designed to deflect radar waves away from the source, thereby reducing the RCS. This is achieved by using faceted surfaces, which are angled to scatter the radar waves in different directions.
Radar-absorbent materials: Special materials are used in the construction of the aircraft, which are designed to absorb radar waves. These materials are typically composed of carbon fiber or other composites.
Engine placement: The engines are often placed inside the aircraft, or are shielded by structures, to reduce their radar signature.
Low-observable coatings: The aircraft is coated with a special material that absorbs radar waves and reduces the RCS.
When a radar system sends out a signal, it bounces off the aircraft and returns to the radar receiver. The receiver analyzes the returned signal to determine the location and characteristics of the object. With stealth technology, the returned signal is weakened, scattered or absorbed, making it difficult for the radar system to detect the aircraft.
Chaff is another technique used to avoid radar detection. It is a cloud of small, metallic or plastic strips that are released from the aircraft. When the strips are in the air, they reflect radar signals, creating a false target and confusing the radar operator. The chaff strips are designed to have a similar RCS to the aircraft, making it difficult for the radar system to distinguish between the aircraft and the chaff. This can provide the aircraft with a temporary advantage, allowing it to evade detection or missile attacks
