Abstract: According to an aspect, method of enhancing a resolution in a radar system having an antenna aperture comprises measuring a first radiation pattern corresponding to a first set of receiving antennas by feeding a known radio frequency (RF) signal over the first set of receiving antennas, wherein the first set of radiation due to an impairment, coherently combining an interpolated radiation pattern with a received radar signal received by the set of receiving antenna when employed for an object detection, to generate a high signal to noise ratio (SNR) received signal, and iteratively combining the high SNR received signal with the interpolated signal to reduce the error due to the impairment.

Abstract: A method of processing received satellite signals is provided. The method includes detecting frequency, power level, code phase and doppler frequency of a plurality of satellite signals and frequency and power level of a plurality of spurious signals. The plurality of spurious signals is ranked based on one or more ranking parameters. A first subset of the plurality of spurious signals which are ranked equal or above a threshold rank are processed through a plurality of notch filters and a second subset of the plurality of spurious signals which are ranked below the threshold rank are processed through a weeding filter.

Abstract: A novel and useful apparatus for and method of minimizing the impact of interference on the phase error performance in a phase locked loop (PLL) at integer channels by adjustment of the phase of the interfering signal such that its impact on the reference signal is minimized. Phase control is achieved by use of the digital architecture of the ADPLL and its insensitivity to an arbitrary phase bias introduced between its digitally represented output and reference phase signals. The optimal phase relationship for each integer channel is determined through a calibration procedure in which the phase is swept and the optimal phase is recorded. Before the transmission of a payload on an integer channel, the phase relationship between the output RF signal and the input reference signal is adjusted to the value found to be optimal for that frequency, based on the values previously recorded during the calibration procedure.
