  "textContent": "A computer-implemented method when executed by data processing hardware causes the data processing hardware to perform operations. The operations include receiving, via a radar system of a vehicle, radar data, identifying, via a hazard alert algorithm, multipath clusters based on the radar data, and estimating, via the hazard alert algorithm, a local reflection coefficient for one or more of the multipath clusters. The operations also include comparing, via the hazard alert algorithm, the local reflection coefficient to a global reflection coefficient stored by a hazard alert system, identifying, based on the comparison of the local reflection coefficient with the global reflection coefficient, an abnormality, and updating a hazard list of the hazard alert algorithm with the identified abnormality. The operations further include estimating, based on the updated hazard list, a hazard type and issuing, via the hazard alert algorithm, an alert including the estimated hazard type.",
