“…Flexible adaptation of the radar hardware architecture and ramp signals to different application scenarios is difficult. For this problem, in the previous work [12], [13], we proposed a soft synchronization frequency modulated continuous wave (SS-FMCW) radar, which is an improved FMCW radar with structural flexibility and signal diversity. Specifically, the SS-FMCW radar adopts a software synchronization method to get rid of the hardware synchronization signal link.…”

“…The signal waveform of the platform is flexible, but its hardware structure lacks flexibility. To this problem, we design the SS-FMCW radar in the subsequent work [13], which not only has the diversity of signal design, but also gets rid of hardware synchronous signal link. Then, we verify the scientific and effectiveness of the radar through theoretical analysis and practical testing.…”

Soft synchronization frequency modulated continuous wave (SS-FMCW) radars not only have the diversity of transmit signals, but also have the flexibility of hardware structure. This article proposes a power consumption model for further analyzing the power performance of the SS-FMCW radar, which is a modulelevel model designed for intermittent ramp signals. First, based on the principle behind the SS-FMCW radar, we build the power consumption model of the radar transmitter and receiver according to the characteristics of intermittent ramp signals. Second, to analyze the power consumption performance of the SS-FMCW radar, we propose a duty cycle factor. In addition, we compare the power consumption performance of traditional frequency modulated continuous wave (FMCW) radar and the SS-FMCW radar with different factor values through theoretical analysis. Finally, the rationality of the theoretical analysis is verified by simulation experiments and actual test experiments. The experimental results show that the SS-FMCW radar has obvious advantages in power consumption performance compared with the traditional FMCW radar. Specifically, when D p = 0.5, compared with the traditional FMCW radar, the power consumption of the SS-FMCW radar is reduced by 18.6% in the actual test experiments. INDEX TERMS power consumption model, soft synchronization frequency modulated continuous wave (SS-FMCW) radar, intermittent ramp signals, duty cycle factor.

“…Its unique features make it suitable for a wide range of applications, including vehicle radars 21 , intelligent devices 22 , and medicare sensors 23 . For example, it is attractive to integrated mmWave Doppler radar sensors into irregular surfaces (e.g., vehicle door panels and bumpers 24,25 ) directly without any other brackets. However, the implementation of commercial mmWave radar sensors generally relies on traditional materials and printed circuit board (PCB) technologies 26 , which is rigid in nature with limitations in terms of form-factor.…”

Flexible hybrid electronics (FHE) is an emerging technology enabled through the integration of advanced semiconductor devices and 3D printing technology. It unlocks tremendous market potential by realizing low-cost flexible circuits and systems that can be conformally integrated into various applications. However, the operating frequencies of most reported FHE systems are relatively low. It is also worth to note that reported FHE systems have been limited to relatively simple design concept (since complex systems will impose challenges in aspects such as multilayer interconnections, printing materials, and bonding layers). Here, we report a fully 3D-printed flexible four-layer millimeter-wave Doppler radar (i.e., a millimeter-wave FHE system). The sensing performance and flexibility of the 3D-printed radar are characterized and validated by general field tests and bending tests, respectively. Our results demonstrate the feasibility of developing fully 3D-printed high-frequency multilayer FHE, which can be conformally integrated into irregular surfaces (e.g., vehicle bumpers) for applications such as vehicle radars and wearable electronics.

본 논문에서는 COTS(commercial off-the-shelf) 부품을 사용하여 C-Band에서 동작하는 경제적인 아두이노 기반의 FMCW(frequency modulated continuous wave) 레이다 시스템 설계를 제안한다. 제안하는 레이다 시스템은 다층 FR4 PCB 공정을 이용한 표면 실장 부품과 모놀리식 IC로 구성된다. 송수신(Tx/Rx) 안테나는 상용 깡통을 이용한 캔테나 (cantennas)를 사용하였으며, 원형 도파관의 기본 모드(dominant mode) 분석을 통해서 설계하였다. 설계된 레이다 시스템 은 널리 사용되는 Arduino UNO 플랫폼과 연동되어 범위-시간-강도(range-time-intensity, RTI) 정보를 표시한다. 설계된 레 이다 시스템은 5.827～5.942 GHz 대역에서 송신 전력 13.8 dBm을 송출하며, 기저대역 샘플링 주파수는 4.5 kHz를 사용했 다. 제작된 레이다 시스템이 가지는 최대 탐지 거리는 56.3 m로 측정되었다.
