20160116582 | Radar imaging via spatial spectrum measurement and MIMO waveforms - The proposed MIMO radar imaging method takes advantages of measurement techniques of spatial frequency components of an RF area image from radar returns. To minimize size, weight and power (SW&P), minimum redundancy arrays (MRAs) for both Tx and Rx with unique geometries are proposed. MIMO waveforms are utilized to index the radiated illuminations to a targeted area in the forms of 1-D spatial frequency components. Consequently, the corresponding radar returns from the targeted field of view (FOV) are captured by the Rx MRA. With the knowledge of uniquely designed MRA array geometries, virtual beams are synthesized in Rx processor; usually one Tx and many contiguous Rx fan beams. These virtual beams may be dynamically “moved” to different beam positions. The elongated beam direction for Tx fan beam and that for Rx fan beams are perpendicular to one another. Thus intersections of the Tx fan-beam and many Rx fan-beams are the very areas of radar returns. We refer those areas as virtual beam crosses. Conventional range and Doppler gating processing shall then be applied to the beam crosses concurrently. Radar return pixel-by-pixel within various beam crosses are measured individually. Radar images can then be synthesized. MIMO radars via spatial spectrum measurements are well suited for wide angle surveillance via improved angle estimation and minimum detectable velocity. SDS proposed MIMO radar design concepts on moving platforms can be used for both the line-of sight (LOS) SAR/GMTI applications. For fixed Radar, they are applicable for fixed radars LOS target detection and tracking, or imaging. They may also be useful for OTH maritime target detection and tracking utilizing evaporation duct propagation | 2016-04-28 |

20160116591 | OBJECT DETECTING APPARATUS - An object detecting apparatus includes a distance calculator that calculates a distance to the object, a wave height acquirer that acquires a respective peak value of the plurality of reflected waves, and multiple reflection determiner. When a reflected wave for which a first distance to the object is calculated to be the smallest in the reflected waves is defined as a first wave, and another reflected wave to which a second distance is calculated as twice or more integer times the first distance calculated for the first wave and a difference of the peak value relative to the first wave which is larger than a predetermined value is present in the reflected waves, the multiple reflection determiner determines that multiple reflection is occurring in a second wave or thereafter. | 2016-04-28 |
20160116592 | OPEN LOOP CORRECTION FOR OPTICAL PROXIMITY DETECTORS - An optical proximity detector includes a driver, light detector, analog front-end, sensor(s) that sense correction factor(s) (e.g., temperature, supply voltage and/or forward voltage drop), and a digital back end. The driver drives the light source to emit light. The light detector produces a light detection signal indicative of a magnitude and a phase of a portion of the emitted light that reflects off an object and is incident on the light detector. The analog front-end receives the light detection signal and outputs a digital light detection signal, or digital in-phase and quadrature-phase signals, which are provided to the digital back-end. The digital back-end performs closed loop correction(s) for dynamic variation(s) in gain and/or phase caused by a portion of the analog front-end, uses polynomial equation(s) and sensed correction factor(s) to perform open loop correction(s) for dynamic variations in temperature, supply voltage and/or forward voltage drop, and outputs a distance value. | 2016-04-28 |
