A Novel Comb-line Leaky-wave Antenna for 77 GHz FMCW Automotive Radar System and Comparison with Buttler Beamformers
نویسندگان
چکیده
For a typical frequency modulated continuous wave automotive radar system, design using novel leaky-wave antenna is proposed that has simple, cheap and easy manufacturing structure whose performance compared with two different arrays. The software used were MATLAB CST Microwave Studio. first system was an inset-fed patch array, the second circular array Buttler beamforming network as beam scanning mechanism. simulation results of three designs are obtained range-Doppler method for multi-target scenarios. excels arrays, which offer cheaper simpler solutions industry.

متن کاملHigh-Resolution Angle Estimation for an Automotive FMCW Radar Sensor
This paper introduces the application of high-resolution angle estimation algorithms for a 77GHz automotive long range radar sensor. Highresolution direction of arrival (DOA) estimation is important for future safety systems. Using FMCW principle, major challenges discussed in this paper are small number of snapshots, correlation of the signals, and antenna mismatches. Simulation results allow ...
متن کاملA Novel Two-Beam Scanning Active Leaky-Wave Antenna
A novel two-beam scanning active leaky-wave antenna (LWA) has been developed. This LWA with a two-terminal feeding microstrip line structure is integrated with a varactortuned X-band high-electron mobility transistor (HEMT) voltagecontrolled oscillator (VCO). The signal of the VCO is injected via a T-divider into the radiating element. To excite the first higher order mode, the designed antenna...
