Claim 4:
5. A method for detecting a moving object comprising:
receiving a first signal from a first antenna and a second signal from a second antenna, wherein each of the first antenna and the second antenna is a sectored antenna and are located at a predetermined height from ground level, and wherein each of the first antenna and the second antenna have zero response below the predetermined height;
determining a delay rate spectrum for the first signal and the second signal based on a cross-correlation function followed by a 2D fast Fourier transform (2D FFT) and an observation time period, wherein the cross-correlation function comprises determining at least a delay, a rate, or a combination thereof, between the first signal and the second signal based on a mathematical correlation function, and the observation time period comprises at least a slow object time period and a fast object time period, wherein the delay-rate spectrum comprises at least a plot of a delay value and an amplitude value or at least a plot of a Doppler rate value and the amplitude value, wherein the moving object is detected based on peak values in the plot, the peak values in the plot are determined using a regional maxima associated with the peak value, wherein the correlation function is performed between the corresponding sectors of the first antenna and the second antenna, and wherein a location of the moving object is detected based on the correlation between peaks of the delay rate spectrums of the corresponding sectors of the first antenna and the second antenna, when the mathematical correlation function indicates a correlation coefficient equal to one or more than a threshold correlation value; and
detecting the moving object based on the delay rate spectrum, wherein detecting the moving object further comprises determining one or more of a location coordinate information of the moving object, an angular position of the moving object, and a movement of the moving object.
