A novel simulation technique for UWB-FMCW radar: enhancing through-the-wall detection capabilities
Ultrawideband frequency-modulated continuous-wave (UWB-FMCW) radar is a solution for through-the-wall (TTW) imaging and detection technology. TTW radar is an attractive UWB microwave imaging system that comprises radars capable of localizing and ...

A Design Concept of CNN Counter to Noise Interference in Radar Signals Classification
This article explains the relationship between the noise energy and the size of output feature maps, and advance the concept of compression and dilation of CNN architecture which depends on the balance of noise energy and the number of features. ABSTRACT Radar signals classification plays an increasingly significant role in electronic reconnaissance ...

Millimeter-Wave OFDM-FMCW Radar-Communication Integration System Design
Frequency-modulated continuous wave (FMCW) and orthogonal frequency-division multiplexing (OFDM) technologies play significant roles in millimeter-wave radar and communication. Their combinations, however, are understudied in the literature.

Processing and Resolution Losses Due to Range Cell Migration—Application to Automotive Radar
This study analyzes how range cell migration (RCM) affects pulse compression and Doppler processing in high‐resolution radar systems. Theoretical models including RCM effects are developed for both pulse and frequency‐modulated continuous wave (FMCW) radar. Resolution and processing losses are quantified for FMCW, linearly frequency‐modulated (LFM) and

This paper investigates the impact of common indoor materials on mmWave radar signal behaviour at 77–81 GHz. Experimental results quantify material‐dependent attenuation and reflection effects under line‐of‐sight and non‐line‐of‐sight scenarios, providing actionable guidance for radar deployment and indoor sensing applications.

This study presents RadMoist, a fully contactless framework that estimates volumetric water content with a single low‐cost 77 GHz FMCW radar (TI IWR1443BOOST, 4 GHz sweep and 3.8 cm range resolution). Beyond conventional surface amplitude and time of flight (ToF), RadMoist introduces three physics‐guided indices: Microangular backscatter slope ($\mu ...
