A method and apparatus of measuring a distance to a reflection object is disclosed. A sensitivity time control (STC) process is applied to a received signal from the reflection object to provide an STC-processed signal. The radar apparatus includes a controller. The controller obtains a quantity corresponding to the distance from a transmission time of the transmission signal and a detection time of the STC-processed signal. The quantity is corrected by using a first correction value associated with the intensity of the STC-processed reflection signal to provide a corrected quantity. The corrected quantity is further corrected by using a second correction value associated with the corrected quantity and the intensity of the STC-processed reflection signal to correct the error regardless of the intensity of the STC-processed reflection signal.
A method of measuring a distance to a reflection object in a radar apparatus which transmits a transmission signal and applies a sensitivity time control (referred to as “STC”) process to a reflection signal from said reflection object to yield an STC-processed reflection signal, the method comprising the steps of:
An apparatus for measuring a distance to a reflection object, the apparatus includes;
