Hidden fatal injury detection method and detection system based on UWB biological radar

Abstract

The invention discloses a hidden fatal injury detection method and detection system based on UWB biological radar, and belongs to the technical field of biological radar. The method comprises the steps: collecting two groups of UWB biological radar echo data, which are in bilateral symmetry, of a physiological anatomical structure of a target to-be-detected object; performing normalization processing, discrete cosine transform processing and threshold operation processing on the two groups of acquired UWB biological radar echo data in sequence to obtain two groups of characteristic value data which can be used for linear discriminant analysis; and performing linear discriminant analysis on the obtained two groups of characteristic value data and then judging an injury condition, if the two groups of characteristic value data are linearly inseparable, judging that no injury condition exists, and if the two groups of characteristic value data are linearly separable, judging that the injury condition exists. According to the invention, data is measured, processed and analyzed by using the symmetry characteristic of a human body plane structure, and automatic discrimination of injury information such as an air layer and a bleeding point is realized so that detection of a fatal hidden injury can be quickly and conveniently realized.

Description

technical field [0001] The present invention belongs to the technical field of biological radar, in particular to a concealed fatal injury detection method and detection system based on UWB biological radar. Background technique [0002] Due to the limitation of personnel, time and conditions in the pre-hospital emergency process, some hidden fatal injuries such as tension pneumothorax and intracranial hemorrhage cannot be detected and correctly diagnosed in time only by the symptoms and signs of the wounded, thus delaying diagnosis and treatment and causing casualties. However, conventional clinical diagnostic techniques and equipment such as ultrasound, X-ray, CT, and MRI are difficult to apply due to the comprehensive limitations of their size, weight, cost, and the need for professional use. [0003] Bioradar is a new concept radar technology that mainly takes the human body as the detection object. It uses electromagnetic waves as the detection medium, which can penetra...

Problems solved by technology

[0004] At present, bio-radar is used for human injury detection using imaging methods. Due to the need for complex multi-channel transceivers, antenna arrays and imaging algorithms, it is difficult to be practical in the short term and is also easily subject to comprehensive limitations such as volume, weight, and cost.
