Signal Source Space Sensing for Active Imaging Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional active sensing systems face signal distortion issues due to external environmental influences and system errors during signal transmission, leading to inaccuracies in sensing and imaging processes.
Innovation Solution
A signal source space sensing method and apparatus that involves a controller-connected signal transmitter and receiver, where a first signal is transmitted to an object, and a second signal is received and mapped back to the signal source space to determine the coordinate relationship between the object's spatial position and the signal source space, allowing for signal reconstruction and minimizing distortion.

1Measurement precision
If traditional active sensing methods are used with transmitters and receivers, then sensing can be performed with controllable signal intensity and direction, but signal distortion occurs due to external environmental influences and system errors during signal transmission
Solution Approach 1:
The patent creates a virtual signal source space that copies the characteristics of the original signal source, allowing signals to be processed as if they originated from the intended source position. This virtual copying approach reconstructs the original signal characteristics by mapping received signals to their expected source coordinates, thereby eliminating distortion caused by environmental factors and system errors while maintaining the controllable signal intensity and direction benefits of traditional active sensing
Solution Approach 2:
The patent introduces a signal source space as an intermediary coordinate system between the physical signal transmission path and the sensing processing. This intermediary space acts as a virtual reference frame where distorted received signals are mapped and corrected based on their relationship to the original signal source coordinates, effectively mediating between the distorted physical signal and the required accurate sensing output

AI summary
Provided are a signal source space sensing method and apparatus, and an active sensing system. The method includes: a controller controls a signal transmitter to transmit a first signal to an object to be tested; the controller controls a signal receiver to receive a second signal, which is obtained after the first signal is transmitted by the object; the controller determines a coordinate relationship between the spatial position of said object and a signal source space according to the first signal and the second signal, wherein the signal source space is a coordinate space where the first signal transmitted by the signal transmitter is located; and the controller maps the second signal back to the signal source space according to the coordinate relationship between the spatial position of the object and the signal source space, to obtain a signal source space signal so as to reconstruct a sensing signal.
