A transmitter of a radar system repeatedly transmits a first OFDM symbol into a scene to be characterized during a first time interval, and repeatedly transmits, during a second time interval that occurs after the first time interval, a second OFDM symbol into the scene. A receiver of the radar system generates a first channel response estimate for a first section of the scene based on: received reflections of the first symbol, at least one of which was received during transmission of the second OFDM symbol in the second time interval, and a first channel response estimate for a second section of the scene based on the first channel response estimate for the first section of the scene, received reflections of the first symbol, and received reflections of the second symbol. The receiver detects objects present in the scene based on the first channel response estimate for the first section of the scene and the first channel response estimate for the second section of the scene.
