Chapter 11: OTFS Radar Fundamentals

Learning Objectives

• Define the ambiguity function and its role in radar waveform design
• Derive the OTFS ambiguity function and establish its thumbtack shape
• Contrast OTFS and OFDM ambiguity functions for joint range-velocity estimation
• Connect range resolution to bandwidth $W$ and velocity resolution to frame duration $T$
• Identify the unambiguous sensing region and its relation to DD grid extent
