In wireless sensor networks (WSN), location information is important to ensure both performance and efficiency of WSN. This paper presents a new positioning method in WSN with reasonable implementation cost and excellent performance. Given a few beacon nodes with known locations and node range estimates based on beacon signals, all nodes' location information can be derived in a passive active mode by solving a set of circle equations through data propagation. Time synchronization is not necessary for all sensor nodes. The dilution of precision for beacon nodes is also discussed. This technique is cost-efficient, scalable and easy to implement. The simulation results show that the proposed method is fast convergent and precise.

“…W-Band (75-110 GHz) radar sensors have been shown to be far superior to the sensors using the optical and infrared system for the sensor operation in degraded visibility conditions and are very attractive due to their high resolution and compact size [1,2]. They are widely-used in automotive cruise control, smart bombs, and millimeter-wave imaging applications, and most of them adopt the homodyne frequency modulation continuous wave (FMCW) method [3][4][5].…”

“…The FMCW (Frequency-Modulated Continuous Wave) radar technology has found widespread applications from detecting vehicle range to monitor of gas-assisted injection molding process with operating frequencies ranging from microwaves to millimeter waves [1,2,3,4]. Recently the ITS (Intelligent Transportation System) group proposed the deployment of Xband FMCW sensor for detection of vehicle volume, occupancy, speed, and classifications of multi-lane highway transportation system.…”

“…Recently the ITS (Intelligent Transportation System) group proposed the deployment of Xband FMCW sensor for detection of vehicle volume, occupancy, speed, and classifications of multi-lane highway transportation system. Although most of FMCW-based sensors known to date had been made by the hybrid microwave/millimeter-wave integrated circuits [5], literature survey indicated that a handful of FMCW chips were reported, namely, 94 GHz radar [1,3,4], 77 GHz sensor [6,7], 10 GHz radar [8], 4.8 GHz Doppler sensor [2], all made by GaAs MMIC (monolithic microwave/millimeter-wave integrated circuit) technology. To authors' best knowledge, we present the first CMOS multifunction chip for use in RF front-end of the FMCW-based sensor or radar.…”

A fully integrated, miniaturized, low-power frequency-modulated continuous wave (FMCW) multifunction chip realized by typical 1P6M 0.18 gm deep n-well CMOS technology is presented for the first time. The multifunction chip consists of VCO, buffer amplifier, 3-dB power divider, isolators, driving amplifiers, mixer, low-noise amplifier, attenuator, etc., necessary for carrying out the X-band RF signal processing of the FMCW signals interfaced to dual antenna arrays. The chip real estate measures 2.4 mm by 1.3 mm. The entire FMCW chip design is based on the synthetic complementary-conductingstrips (CCS) quasi-TEM transmission line. The transmitter output is 3.5 dBm for frequencies between 9.5-11.0 GHz and maximum tuning bandwidth is nearly 150 MHz. The receiver channel has conversion gain of 6 dB. The calculated range is in good agreement with the measurement data.
