Abstract: Described herein is NLS using a bounded linear initial search space and a fixed grid with pre-calculated variables. Specifically, first and second signals with unknown first and second elevation angles, respectively, are received that have been reflected by an object, with the second signal also having been reflected off the ground. A line of second angles is then established as a function of first angles, a sensor height, and a range to the object. The first angles being bound by a function of the sensor height and the range and a function of the sensor height, the range, and the maximum height. A search algorithm is then used to search for an initial elevation angle pair along the line. The initial elevation angle pair may then be fed into a refinement algorithm (e.g., non-linear least squares) to determine the elevation angles associated with the first and second signals.

Abstract: A method includes calculating a discrete Fourier transform (DFT) of radar signals received by radar elements. The method includes identifying a peak amplitude of the DFT and designating a frequency corresponding to the peak amplitude of the DFT as an initial frequency estimate. The method includes selecting first and second neighboring points of the DFT based on the initial frequency estimate. The method includes generating first and second values based on amplitudes of the first and second neighboring points of the DFT. The method includes calculating a generalized interpolation value based on a generalized discrete DFT interpolation. The generalized discrete DFT interpolation is based on the first value, the second value, and the peak amplitude. The method includes generating a fine frequency estimate of the input radar signals by summing the initial frequency estimate and the generalized interpolation value.

In certain embodiments, a MEMS gyroscope includes a resonator mass that moves in a first direction (for instance, x-direction), a sensing structure that detects a Coriolis effect in a second direction (for instance, y-direction), and a plurality of electrodes that control a cross-axis stiffness of the MEMS gyroscope by controlling motion of the resonator mass in a third direction (for instance, z-direction). For example, the electrodes can be used to reduce or eliminate cross-axis sensitivity arising from cross-axis stiffnesses, such as kxz (resonator-to-orthogonal) and/or kyz (Coriolis-to-orthogonal).
