A radar system comprises a transmitter antenna configured to transmit a radio frequency (RF) signal, a first receiver antenna, and a second receiver antenna. Each of the first and second receiver antennas are configured to receive a reflection of the RF signal, wherein the first and second receiver antennas are synchronized and separated by a vertical distance. The radar system also comprises radar processing circuitry configured to control transmission of the RF signal from the transmitter antenna and to determine an elevation of an object reflecting the RF signal based on the phase difference between the reflected RF signal received by the first receiver antenna and the reflected RF signal received by the second receiver antenna; wherein the transmit antenna, first receiver antenna, and second receiver antenna are operable to continuously rotate 360 degrees along an azimuth angle without rotating along an elevation angle.

What is claimed is: 1. A radar system comprising:a transmitter antenna configured to transmit a radio frequency (RF) signal;a first receiver antenna coupled to a first receiver;a second receiver antenna coupled to a second receiver; each of the first and second receiver antennas configured to receive a reflection of the RF signal, wherein the first and second receiver antennas are synchronized and separated by a vertical distance; andradar processing circuitry coupled to the first receiver antenna and the second receiver antenna via the first receiver and the second receiver, respectively, the radar processing circuitry configured to control transmission of the RF signal from the transmitter antenna and to determine an elevation of an object reflecting the RF signal based on the vertical distance separating the first receiver antenna from the second receiver antenna and on a phase difference between the reflected RF signal received by the first receiver antenna and the reflected RF signal received by the second receiver antenna;wherein the transmit antenna, first receiver antenna, and second receiver antenna are operable to continuously rotate up to 360 degrees along an azimuth angle without rotating along an elevation angle.
