Özet
Weight on Wheels (WoW) systems are pivotal in aircraft landing, ensuring timely control actions and safety measures. Accurate touchdown estimation is critical, demanding fail-safe mechanisms with multiple redundancies. For unmanned aerial systems (UAS), where size, weight, and power (SWaP) metrics are paramount, software redundancies offer a viable solution with minimal SWaP overhead. FrequencyModulated Continuous Wave (FMCW) Radar Altimeters are crucial for UAS landing approaches. Leveraging software-defined architectures and prioritizing WoW safety requirements, radar waveform specifications can be tailored for precise touchdown detection in UAS, aligning with software redundancy principles. While Zoom FFT (ZFFT) traditionally conserves resources by focusing on specific spectrum portions, this study proposes an alternative approach for millimeter-level range accuracy on mmWave FMCW automotive radar. It includes derivation of waveform specifications from operational requirements, methodological insights, theoretical discourse, and experimental hardware results. The article concludes with authors' discussion and future research directions. © 2024 IEEE.
