Abstract: A method of processing radar signalling, the method comprising: receiving a mask (815) that represents samples in the radar signalling that are detected as including interference. The mask (815) comprises a matrix of data having a first dimension and a second dimension, wherein the first dimension represents a fast-time axis and the second dimension represents a slow-time axis. The method further comprises performing frequency analysis on the mask (815) across each of the fast-time axis and the slow-time axis of the mask in order to provide a range-Doppler processed mask (817); and deconvolving a range-Doppler map (813) of the received radar signalling using the range-Doppler processed mask (817) in order to provide a deconvolved-range-Doppler map (814).

Abstract: A mechanism is provided for determining an unambiguous direction of arrival (DoA) for radio frequency (RF) signals received by a sparse array. A DoA angle domain is split into hypothesis regions. The hypothesis regions are derived from the phase differences of the antenna element pairs used for the DoA angle estimate. In each hypothesis region, the ambiguous phase of antenna element pairs is unwrapped according to expected wrap-around. After unwrapping the phase, for each hypothesis region, a phasor is calculated by combining the individual antenna element pair phasors. The hypothesis region that obtains the phasor with a largest amplitude is selected as the most likely DoA region and the phase of the winning phasor is used as an unambiguous estimate for the DoA angle.

Abstract: A processing module for a receiver device is disclosed. The processing module is configured to provide for processing of a signal received by the receiver device from a transmitter device. The signal includes a secure training sequence divided into a plurality of time spaced blocks. The secure training sequence incoudes a non-repeating pattern of symbols. The processing module is configured to, based on a first phase marker in the first block and a second phase marker in the second block defining a phase difference of the signal between the first and second antennas and a known spacing of the first antenna relative to the second antenna, determine an angle of arrival of the signal relative to the receiver device.
