Abstract
A Doppler radar calibrator includes: an operator input device for specifying motion of a Doppler radar calibrator target; a motion controller connected to the operator input device and to the Doppler radar calibrator target, the motion controller receiving information from the operator input device and causing motion of the Doppler radar calibrator target based on the information received; and a Doppler radar calibrator target, wherein the Doppler radar calibrator target moves with a selected frequency and displacement amplitude based on information from the motion controller.
Claims22
A Doppler radar calibrator 203, comprising:
- an operator input device 200 for specifying motion of a Doppler radar calibrator target 202;
- a motion controller 201 connected to the operator input device 200 and to the Doppler radar calibrator target 202, the motion controller 201 receiving information from the operator input device 200 and causing motion of the Doppler radar calibrator target 202 based on the information received;
- and a Doppler radar calibrator target 202, wherein the Doppler radar calibrator target 202 moves with a frequency from 0.1 Hz to 10 Hz and the Doppler radar calibrator target 202 moves with a displacement amplitude from 0.5 cm to 2 cm based on information from the motion controller 201.
A process for operating a Doppler radar calibrator 203, comprising:
- receiving information from an operator input device 200 to define a motion of a Doppler radar calibrator target 202;
- transmitting the information to a motion controller 201;
- converting the information by the motion controller 201 into information for actuating a Doppler radar calibrator target 202;
- and actuating the Doppler radar calibrator target 202 by the motion controller 201 to move the Doppler radar calibrator target 202 with a frequency from 0.1 Hz to 10 Hz and with a displacement amplitude from 0.5 cm to 2 cm.
A process for determining whether an unknown Doppler radar system 204 is calibrated, the process comprising:
- illuminating a Doppler radar calibrator target 202 with a test source radio frequency wave 205;
- actuating the Doppler radar calibrator target 202 by a Doppler radar calibrator 203 to move the Doppler radar calibrator target 202 with a frequency from 0.1 Hz to 10 Hz and with a displacement amplitude from 0.5 cm to 2 cm to produce a test reflected radio frequency wave 206 having a test Doppler shift 207;
- receiving the test reflected radio frequency wave 206 by the unknown Doppler radar system 204;
- and determining a Doppler shift by the unknown Doppler radar system 204.
