Method, system and device for radar based high resolution object detection
First Claim
1. A Radar transceiver for an object detection comprising:
- a two dimensional antenna array receiving plurality of a reflected radio frequency (RF) signals;
a mux-adder selectively adding the reflected RF signals in a first mode and selectively multiplexing the reflected RF signals in a second mode;
a range bin detector determining a valid range bins and velocity in the first mode; and
a three dimensional (3D) image reconstructor operating on the valid range bins to reconstruct a 3D image of the object in the second mode.

Abstract
In an embodiment of the present disclosure, a Radar transceiver for object detection comprises a two dimensional antenna array receiving plurality of a reflected radio frequency (RF) signals, a mux-adder selectively adding the reflected RF signals in first mode and selectively multiplexing the reflected RF signals in a second mode, a range bin detector determining a valid range bins in the first mode and a three dimensional (3D) image reconstructor operating on the valid range bins to reconstruct a 3D image of the object in the second mode. In that the two dimensional antenna array comprises antenna elements arranged in K rows and M columns, and the mux-adder adds a RF signal received on the M columns of each row in the first mode. The mux-adder multiplexes the RF signal received on the M columns of each row in the second mode.
