Power Consumption Model Construction and Analysis for Soft Synchronization FMCW Radar

Abstract

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.

Detection and Determination of User Position Using Radio Tomography with Optimal Energy Consumption of Measuring Devices in Smart Buildings

“…An example of the opposite of such a technology could be, for example, UWB technology, which guarantees high accuracy but is still strictly dependent on the user's device [12]. The solution presented here combines the advantages of both previously mentioned technologies while maintaining a relatively low level of control system complexity [13][14][15]. The justification for this approach is to reduce building maintenance costs and increase rational management of energy resources, thus relieving the environment.…”
