24 GHz Millimeter Wave Radar Altimeter

Functional Characteristics

The millimeterwave radar altimeter operates in the 24 GHz frequency band. It is applied to UAV platforms to measure the height of the UAV platform relative to the ground. This radar transmits Frequency Modulated Continuous Wave (FMCW) signals and receives echo signals reflected from ground targets to measure the realtime height of the UAV. It features advantages including compact size, light weight, low power consumption, allweather and alltime operation.
