The underlying concept of the radar altimeter was developed independent of the wider radar field, and originates in a study of long-distance telephony at Bell Labs. During the 1910s, Bell Telephone was struggling with the reflection of signals caused by changes in impedance in telephone lines, typically where equipment connected to the wires. This was especially significant at repeater … WebMar 14, 2024 · Aircraft altitude is continuously monitored and transmitted to an attached radar beacon system. This system consists of a rotating disc that changes its position based on how high or low you fly. Photocells sense this disc rotation, and digital signals are then amplified using the encoded altimeter before they are transmitted.
