Radar Altimeters



CAES provides advanced radar altimeter solutions capable of high accuracy altitude measurements in adverse conditions.  Our radar altimeters are used in UAVs, space launch applications, autonomous targets and towed targets. The linear FM (Chirped) Radar Altimeter (RALT) product line uses modular construction and advanced digital signal processing (DSP) techniques to provide a small volume, low power consumption, high performance RALT.

The Transmitter employs Adaptive Power Control (APC) to minimize transmit power over the full altitude range in adverse weather conditions. The DSP dynamically controls APC, transmitter sweep rate and deviation, to provide an accuracy of one foot or better at low altitudes. The RALT is programmable with features that are defined by the end-user.
