Two-stage code reference beamformer for the reception of frequency hopping modulated signals

Abstract: This paper presents a beamforming technique for the reception of frequency hopping (FH) modulated signals, which takes advantage of their inherent frequency diversity. This technique, based on a code reference beamformer, requires neither temporal nor spatial a priori reference and allows continuous self-calibration of the array. The proposed framework is composed of two di!erent stages. The "rst stage employs the inverse of the noise plus interference covariance matrix obtained by an anticipative processor. T… Show more

“…As a result, the periodic grating lobes are transformed into sidelobes and the restriction on the product of frequency step and pulse width is naturally broken. Thanks to the inherent diversity and flexibility in frequency domain, hopped‐frequency waveforms are potentially favourable for interference rejection and sidelobe suppression [8].…”
