Abstract

The invention provides a speed determining method for a movement object, and a mobile terminal, and relates to the technical field of communication. The speed determining method for the movement object comprises the following steps: receiving a reflection wave, which is reflected by the movement object, of an emission wave emitted from the first antenna, the second antenna and the third antenna ofthe mobile terminal, wherein the installation positions of the mobile terminals where the first antenna, the second antenna and the third antenna are positioned are not positioned on the same straight line; according to the frequency of the emission wave, the frequency of the reflection wave and the installation positions of the mobile terminals where the first antenna, the second antenna and thethird antenna are positioned, determining the movement speed of the movement object. The scheme of the invention is used for solving the problems that a result obtained by an existing speed determining way is low in accuracy, and system performance is affected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for determining the speed of a moving object and a mobile terminal. Background technique [0002] With the rapid development of communication technology, the functions of mobile terminals are becoming more and more diversified, which brings great convenience to people's life. Among them, the realization of various functions needs to rely on the speed judgment of the moving object near the mobile terminal, such as the recognition of the moving object during shooting. [0003] However, the speed determination of the existing moving object is mainly through the images collected by the camera or the monitoring data of the sensor, and the speed of the moving object is calculated according to the front and rear positions of the moving object and the time consumed for moving. However, the calculated speed is the average speed during the moving process of the moving obje...
