“…20 This harmonic tag 21,22 emits information using the harmonics of the fundamental signals transmitted by the harmonic radar system. Harmonic radars [23][24][25] are a kind of nonlinear radar 26 that transmits a fundamental frequency, which will act as the carrier frequency, and the information signal of the target is received on the radar by a tone harmonic of the fundamental as the carrier frequency. In other words, the reception carrier frequency will be a harmonic tone of the fundamental frequency.…”

Nonlinear radar technology has been employed in various applications for a few decades, primarily focusing on second-order harmonic radar systems. This study delves into the potential benefits and drawbacks of utilizing higher-order harmonic radar systems. We present a comparative analysis between second-and third-order harmonic systems using Cadence AWR Visual System Simulator (VSS) followed by experimental validation. In the experiments, target emulation is achieved through nonlinear tags. In contrast, cluttered environments near the targets are simulated using corner reflectors, with the tag and the corner reflector moving at different frequencies facilitated by Zaber linear actuators. Our findings reveal both the advantages and limitations associated with higher-order systems, offering valuable insights into an underexplored area of research within the domain of harmonic radar technology. This contribution addresses the existing gap in the literature pertaining to higher-order harmonic radars by providing comparative analyses using both measurement and simulation data.

First SIMO Harmonic Radar Based on the SFCW Concept and the HR Transfer Function

This paper presents a new SIMO radar system based on a harmonic radar (HR) stepped frequency continuous wave (SFCW) architecture. Simple tags that can be electronically individually activated and deactivated via a DC control voltage were developed and combined to form an MO array field. This HR operates in the entire 2.45 GHz ISM band for transmitting the illumination signal and receives at twice the stimulus frequency and bandwidth centered around 4.9 GHz. This paper presents the development, the basic theory of a HR system for the characterization of objects placed into the propagation path in-between the radar and the reflectors (similar to a free-space measurement with a network analyzer) as well as first measurements performed by the system. Further detailed measurement series will be made available later on to other researchers to develop AI and machine learning based signal processing routines or synthetic aperture radar algorithms for imaging, object recognition, and feature extraction. For this purpose, the necessary information is published in this paper. It is explained in detail why this SIMO-HR can be an attractive solution augmenting or replacing existing systems for radar measurements in production technology for material under test measurements and as a simplified MIMO system. The novel HR transfer function, which is a basis for researchers and developers for material characterization or imaging algorithms, is introduced and metrologically verified in a well traceable coaxial setup.
