A Unique Approach to Freqeucny-modulated Continuous-wave Radar Design
Frequency-Modulated Continuous-Wave (FMCW) Radar has traditionally been used in short range applications. Conventional FMCW radar requires the use of expensive microwave mixers and low noise amplifiers. A uniquely inexpensive solution was created, using inexpensive Gunn oscillator based microwave transceiver modules that consist of 3 diodes inside of a resonant cavity. However these transceiver...
متن کاملDesign of FMCW Radars for Active Safety Applications
With 28.000 road fatalities in 2012 in Europe, car manufacturers, automotive electronics suppliers, and universities are working to develop new electronic systems for accident prevention and collision mitigation. In the near future, vehicle-tovehicle and vehicle-to-infrastructure networks based on dedicated short-range communication (DSRC) technology will warn drivers when dangerous conditions ...
متن کاملOn the Sensitivity Degradation Caused by Short-Range Leakage in FMCW Radar Systems
Frequency modulated continuous wave (FMCW) radar systems suffer from permanent leakage due to their continuous operation. Especially in integrated circuits this leads to the well known issue of on-chip leakage due to limited isolation between transmit and receive circuitry. In addition, we investigate short-range (SR) leakage resulting from signal reflections of an unwanted close object located...
متن کاملShort-Range Noncontact Sensors for Healthcare and Other Emerging Applications: A Review
Short-range noncontact sensors are capable of remotely detecting the precise movements of the subjects or wirelessly estimating the distance from the sensor to the subject. They find wide applications in our day lives such as noncontact vital sign detection of heart beat and respiration, sleep monitoring, occupancy sensing, and gesture sensing. In recent years, short-range noncontact sensors ar...
متن کاملA Multi-beam and Multi-range Radar with Fmcw and Digital Beam Forming for Automo- Tive Applications
In this paper, we propose a multi-beam and multi-range (MBMR) radar with frequency modulated continuous wave (FMCW) waveform and digital beam forming (DBF) algorithm to cover a detection area of long range and narrow angle (150 m, ±10◦) as well as short range and wide angle (60 m, ±30◦) as a single 24 GHz sensor. The developed radar is highly integrated with multiple phased-array antennas, a tw...
