BYU micro-SAR: A very small, low-power LFM-CW Synthetic Aperture Radar
… on a small UAV. To meet these constraints, a linear frequency modulation-continuous wave (LFM-CW) transmit signal is utilized. Use of an LFM-CW signal introduces some differences from the typical strip map SAR processing model that must be addressed in signal processing algorithms. This thesis …

Stepped-frequency pulse train waveforms for improved radar range resolution
… of improving radar range resolution using a linear frequency modulated chirp signal requires the full width of the frequency spectrum, which is not feasible in the UHF band due to interference or frequency allocation for other purposes. In this study a linear frequency modulated chirp signal …

Spectrum Awareness: Deep Learning and Isolation Forest Approaches for Open-set Identification of Signals
… waveform (Single-Carrier (SC), Single-Carrier Frequency Division Multiple Access (SC-FDMA), Orthogonal Frequency Division Multiplexing (OFDM), Amplitude Modulation (AM), Frequency Modulation (FM)) or a radar waveform (Linear Frequency Modulation (LFM) or Phase-coded). However, the downside to …

Implementation of the Transmitting Functionality on the TIGER-3 FPGA-based Transceiver Platform
High Frequency (HF) radio waves (3-30 MHz) are commonly used in long-range communication applications or in radars that require long-range detection capabilities. This is due to the refraction of HF radio waves, where the transmitted wave bends back towards to the Earth. HF radio waves can …
