LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Radar aeroecology - the use of radar to study airborne life, like birds, bats, and bugs Radar ornithology - the use of radar to study birds, especially bird migration Dual-polarization radar - radar that transmits and receives waves in both a horizontal and vertical orientation, giving a better idea of a target’s size, shape, and variety. Doppler effect - a change in a wave’s frequency in relation to whatever is observing it, such as a radar, but also your ears (it’s the reason a sound like an ambulance siren changes as it gets closer or further away from you).
