摘要： A radar altimeter (10) is described which includes a transmitter (12) for transmitting a radar signal, a receiver for receiving the reflected radar signal, and at least one antenna (20, 24) coupled to one or both of the transmitter and receiver. The altimeter also includes a forward facing millimeter wave (MMW) antenna (34) configured to move in a scanning motion and a frequency up/down converter (18) coupled to the MMW antenna, the transmitter, and the receiver, and a radar signal processor (30). The converter up converts a frequency received from the transmitter to a MMW frequency for transmission through the MMW antenna, and down converts frequencies received to a radar frequency which are output to the receiver. The radar signal processor controls scanning motion of the MMW antenna, processes signals received at the antenna for a portion of the scanning motion, and processes signals received at the MMW antenna for other portions of the scanning motion.

摘要： An apparatus (100) for calibrating a radar altimeter (10) is described. The altimeter provides an angle to a target based on radar energy received at right (20), left (16), and ambiguous (18) antennas. The apparatus comprises a turntable (104) on which the radar is mounted, a turntable controller (106) which controls positioning of the radar altimeter, a radar energy source receiving transmit signals (110) from the radar altimeter, a reflector (122), and a calibration unit (128). The reflector reflects and collimates radar energy (124) from the radar source towards the radar altimeter. The calibration unit receives an angle (108) from the controller indicative of a position of the radar altimeter with respect to the collimated radar energy and a measured angle (126) from the radar altimeter. The calibration unit calculates a correction (72) based on differences between the angle received from the turntable and the measured angle received from the altimeter and provides the calibration correction to the altimeter.
