摘要： For use in conjunction with a microwave antenna having a radiator array configured to scan in a horizontal direction, a method for scanning in the vertical direction. A first FMCW microwave signal having a first bandwidth is transmitted at a first microwave frequency and the echo, if any, is received by the radiator array. A second FMCW microwave signal having a second bandwidth is also transmitted at a different center frequency and the echo, if any, is received by the radiator array. The different frequencies cause an elevational shift in the received signal. The receipt of the echoes is then processed to identify the location or locations of the object or objects causing the echo and communicating such location or locations to a user.

摘要： A radar system operable to detect objects within multiple ranges using common components is provided. The radar system includes a transmitter antenna, a first and second microwave radiation source, and a receiver. The first and second microwave radiation sources both are transmitted through the transmitter antenna. The echoes are received by the same receiver. The first microwave radiation source is a frequency modulated wave form and the second microwave radiation source is an ultra-wide band wave form. A multiplexer selectively connects one of the first and second microwave radiation sources to the transmitter antenna.

摘要： A waveguide to microstrip transition having a waveguide open at one end. A dielectric substrate includes a first and a second side and a ground plane covers the first side of the substrate. The dielectric substrate overlies the waveguide opening so that the ground plane faces the waveguide and an opening in the ground plane registers with the waveguide opening. A back short having a housing is positioned on the second side of the dielectric substrate. The back short housing forms a cavity which registers with at least a portion of the ground plane opening so that microwave energy from the waveguide passes through the dielectric substrate and into the cavity defined by the back short housing. The back short housing has at least one opening to the cavity along the second side of the dielectric substrate. A pair of spaced apart microstrips on the second side of the substrate each have a free end positioned in the cavity so that the free ends of the microstrips are spaced apart from each other.

摘要： An example apparatus comprises an electromagnetic source, such as an antenna, a metamaterial lens, and a reflector. The antenna is located proximate the metamaterial lens, for example supported by the metamaterial lens, and the antenna is operable to generate radiation when the antenna is energized. The reflector is positioned so as to reflect the radiation through the metamaterial lens. The reflector may have a generally concave reflective surface, for example having a parabolic or spherical cross-section. The metamaterial lens may have an area similar to that of the aperture of the reflector. In some examples, the antenna is located proximate a focal point of the reflector, so that a generally parallel beam is obtained after reflection from the reflector.
