Problems solved by technology
[0003] However, the radar system collects data signals through an analog-to-digital converter. Due to the limitation of the sampling rate of the analog-to-digital converter, when the sampling interval is too wide, it will cause spectrum overlap, which will cause confusion in the measurement of the target speed by the radar.
Therefore, the speed measurement range of the radar is limited, and it is difficult to meet the needs of practical application scenarios

The invention is suitable for the radar technology field and provides a speed measurement method applied to a radar, a speed measurement device, electronic equipment and a computer readable storage medium. The speed measurement method comprises the following steps of based on the track information of a target, calculating the distance change rate of the target; based on the distance change rate, calculating the speed blur multiple of the speed measurement value of the target; and according to the speed blur multiple, carrying out speed deblur and acquiring the real speed of the target. In theinvention, the speed measurement range of the radar can be effectively increased and the application demand of a vehicle-borne radar is satisfied.
Description
Technical field [0001] The invention belongs to the field of radar technology, and in particular relates to a speed measurement method, a speed measurement device, electronic equipment and a computer readable storage medium applied to radar. Background technique [0002] At present, in the civilian direction, radar has been increasingly used in automobiles or other ground-based motor vehicles to achieve auxiliary driving functions such as obstacle detection, collision prediction, and adaptive cruise control. Among them, radar is used to achieve The speed measurement of targets near the vehicle is an important application direction. [0003] However, the radar system collects data signals through analog-to-digital converters. Due to the limitation of the sampling rate of the analog-to-digital converter, when the sampling interval is too wide, it will cause spectrum overlap, which will cause confusion in the radar's measurement of target speed. Therefore, the speed range of the rada...
