==LOW-COST REAL-TIME MILLIMETER-WAVE IMAGING SYSTEM FOR SECURITY BODY SCREENING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240012134 titled 'LOW-COST REAL-TIME MILLIMETER-WAVE IMAGING SYSTEM FOR SECURITY BODY SCREENING

==Simplified Explanation==

The abstract describes a modified back propagation (MBP) method that improves the computational speed of near-field microwave imaging and millimeter wave imaging. It achieves this by employing path dimension reduction and utilizing an inverse fast Fourier transform along the frequency dimension.

* Path dimension reduction is used to reduce the computational workload by employing approximate path ranges instead of highly precise ones. This reduces the computational workload while maintaining image quality.
* The MBP method also utilizes an inverse fast Fourier transform along the frequency dimension, representing frequencies as a minimum frequency plus increments. This further enhances the computational speed of the imaging system.

Potential applications of this technology:
* Real-time imaging systems, including body security screening systems, can benefit from the improved computational speed provided by the MBP method.

Problems solved by this technology:
* The MBP method addresses the computational burden associated with near-field microwave imaging and millimeter wave imaging, allowing for faster image processing and analysis.

Benefits of this technology:
* The modified back propagation method significantly enhances the computational speed of imaging systems, enabling real-time imaging applications.
* By reducing the computational workload, the method improves efficiency without compromising image quality.


==Original Abstract Submitted==

a modified back propagation (mbp) method designed to substantially enhance the computational speed of near-field microwave imaging and millimeter wave imaging. this method leverages two key factors to boost efficiency. firstly, it employs path dimension reduction to diminish computational workload, accomplished by employing approximate path ranges. rather than utilizing numerous highly precise path ranges to calculate phase shifts, this approach selects an appropriate range unit for approximate ranges, resulting in a significant reduction in computational workload with minimal impact on image quality. secondly, it harnesses the power of an inverse fast fourier transform along the frequency (wavenumber) dimension, representing frequencies as a minimum frequency plus increments. through the combination of these two enhancements, the mbp method becomes applicable to real-time imaging systems, including but not limited to body security screening systems.
