Abstract

A target point position detection system (400) is characterized in that the system (400) comprises a signal generating device (401), a phase control array sensor (403) comprising a plurality of sub-elements (402) with set intervals, and a signal processing device (404); the signal generating device (401) is used for applying a preset excitation signal to each sub-element (402) of the phased array sensor (403); each sub-element (402) of the phased array sensor (403) is used for transmitting a mechanical wave signal based on the excitation signal and receiving an echo signal reflected by a target point, and the mechanical wave signal is subjected to interference enhancement at a plurality of preset scanning angles to form a detection beam and meets an orthogonal condition; and the signal processing device (404) is used for analyzing and processing the echo signals received by the sub-elements (402) to obtain the position information of the target point.

Description

technical field [0001] The present specification relates to the field of intelligent perception, and in particular, to a target point position detection system and method, a programmable circuit and a storage medium. Background technique [0002] At present, in the environment perception application of smart devices, the related technology uses phased array technology to obtain the location information of the target point and realize the environment perception. The specific implementation method is as follows: the initial phase is set for each array element of the phased array sensor, and different excitation signals are applied to the array element, so that the sensor emits a detection beam to a certain range of space; the target point located in this range is The detection beam is reflected, and the formed echo signal is received by the array element. Through data processing, the position information of the target point can be obtained. [0003] However, since this method...
