A Low-Cost Angle Super-Resolution FMCW Phased Array Radar Based on TSPW for Automotive Applications

Year: 2024

Type: article

Abstract: A low-cost super-resolution frequency modulated continuous wave (FMCW) phased array radar employing a single radio-frequency (RF) channel sampling scheme is proposed. Since the conventional phased array radar lacks element-level array signals, it cannot achieve angle super-resolution. By exploiting time sequence phase weighting (TSPW) technology, the proposed radar can obtain the element-level array signals without connecting additional transmit/receive (T/R) components to each antenna element, as that in element-level digital arrays. Furthermore, the freedom of the array has been further enhanced by exploiting the nested array structure. Numerical simulation results are presented to demonstrate the effectiveness of the proposed system.
