Why do weather radar antennas have various shapes?

And is suitable for different detection requirements. Weather radar mainly detects meteorological elements and weather phenomena in the atmosphere by emitting electromagnetic waves into the atmosphere and receiving echo signals. Weather radar antennas with different shapes can adapt to different working environments and detection requirements. For example, a parabolic antenna is a common weather radar antenna, which is similar to a parabola in shape and can focus the emitted electromagnetic waves on one point, thus improving the detection accuracy and distance of the radar. In addition, some weather radars also use antennas with different shapes, such as flat antennas and spherical antennas, which can better meet specific detection requirements, such as the detection of low-altitude wind fields and precipitation distribution. In a word, various shapes of weather radar antennas are designed to meet different detection requirements.
