Altimeter radar 4503-100

The CAES 4503-100 is a linear FM (Chirped) Radar Altimeter (RALT), using modular construction, and advanced digital signal processing (DSP) techniques, to provide a small volume, low power consumption, low cost, high performance RALT. The Transmitter employs Adaptive Power Control (APC) to minimize transmit power over the full altitude range. 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. The use of solid-state devices and an efficient thermal design enables the RALT to be operational between -40°C and +71°C temperature with conduction cooling Specifications: Altitude Range: 1 ft. To 4000 ft. typical Accuracy: ± (1ft. + 1% Altitude) Digital Output Typical; ± (1ft. +2% Altitude) Analog Output typical Track Rate: > 2000 ft./sec.
