3D SHORT RANGE DETECTION WITH PHASED ARRAY RADAR |
摘要 |
PROBLEM TO BE SOLVED: To provide a radar microchip capable of a 3D scan.SOLUTION: A radar microchip for short range detection with phased array radar uses phase shifters along with an antenna array to steer the transmitted and received radar beams along orthogonal axes to achieve a 3D scan. Individual phase shifters connected to antenna cells that transmit and receive the radar beams steer the radar along two orthogonal axes by controlling the phase of the radar. The radar then detects where the two beams overlap. The antenna cells are further aligned along these orthogonal axes. An isolation barrier between the phase shifters of the transmitted and received signals reduces cross coupling on the radar microchip. |
