Abstract

Embodiments of the present disclosure are directed to calibrating an imaging and ranging subsystem. Sensor data indicative of one or more targets from the imaging and ranging subsystem, location data defining a geographical location of the imaging and ranging subsystem, orientation data defining an orientation of the imaging and ranging subsystem and stored translation and rotation values of the imaging and ranging subsystem are received. Estimated Doppler values for the target are provided by the sensor data and theoretical Doppler values for the targets are also calculated. The estimated Doppler values are compared to the theoretical Doppler values to determine if calibration of the imaging and ranging subsystem is required. If calibration is necessary, correction translation and correction rotation values are calculated in order to calculate updated translation and rotation values used to calibrate the imaging and ranging subsystem.
