Radar cross section is a measure of the electromagnetic energy intercepted and reradiated at the same frequency
The radar cross section of an object is a measure of how well it reflects or scatters radar signals. A larger radar cross section means the object is more likely to be detected by radar systems.
The effect of directivity is that it leads to earth tremors.

The radar that uses a cross-shaped beam is known as a "crossed beam radar" or "cross-beam radar." This type of radar employs two intersecting beams to improve target detection and tracking accuracy by providing coverage in multiple dimensions. The cross-shaped beam pattern allows the radar to effectively scan a larger area and enhances its ability to distinguish between different targets. This design is often utilized in applications such as air traffic control and weather monitoring.

Radar cross section (RCS) is measured in square meters (m²). It quantifies how detectable an object is by radar, representing the effective area that reflects radar signals back to the source. A larger RCS indicates a greater ability to reflect radar waves, making the object more detectable.
The six target characteristics of radar are range, velocity, azimuth, elevation, size, and radar cross section. Range refers to the distance of the target from the radar system, velocity represents the speed of the target, azimuth and elevation specify the target's horizontal and vertical angles, size indicates the physical dimensions of the target, and radar cross section is a measure of how well the target reflects radar signals.
Go in always the same distance with a loudspeaker and a pure tone arround the microphone and measure the microphone's output. You get a damping curve which is the directivity curve.
Radar cross section.
It is used to detect planes in a wide variation of ranges
The directivity of a small loop antenna is higher than that of a short dipole because the loop antenna is more directional and concentrates radiation in one direction. The ratio can vary depending on the dimensions and configuration of each antenna, but in general, the loop antenna can have a directivity several dB higher than the dipole.
