DOI: 10.1109/lgrs.2022.3151679
Abstract: Waveform adaptation grants cognitive radar (CR) the ability to adapt to its environment, which requires an effective framework to synthesize waveforms sharing a desired ambiguity function (AF). In this letter, we propose a novel method… read more here.

DOI: 10.1109/taes.2018.2886614
Abstract: Congestion in the RF spectrum is rapidly increasing, which has motivated the need for efficient spectrum sharing techniques. A cognitive radar system has been developed to implement a perception action cycle, for spectrum sharing, in… read more here.

DOI: 10.1109/taes.2020.3031766
Abstract: The growing demand for radio frequency (RF) spectrum access poses new challenges for next-generation radar systems. To operate in a crowded electromagnetic environment, radars must coexist with other RF emitters while maintaining system performance. This… read more here.

DOI: 10.1117/1.jrs.12.045013
Abstract: Abstract. We deal with the unimodular waveform design for cognitive radar in signal-dependent interference (clutter). In addition to the signal-to-clutter-plus-noise ratio (SCNR), we also consider the filtered integrated sidelobe level (ISL) and optimize these two… read more here.

DOI: 10.3390/e24050672
Abstract: This article proposes the Bayesian surprise as the main methodology that drives the cognitive radar to estimate a target’s future state (i.e., velocity, distance) from noisy measurements and execute a decision to minimize the estimation… read more here.
