Abstract

A new kind of phased array for automobile radar based on coupled oscillator is introduced which need not phase shifters. The dynamic of nearest-neighbor coupled oscillators array is analyzed and simulated. It is shown that a constant phase gradient can be achieved by detuning the free-running frequency of the edge array elements. A S-band one-dimensional experimental array is presented, giving a measured phase progression among the array that is continuously variable over the range (-60deg, 60deg).
