In an ultra-wideband (UWB) communication system, methods are disclosed for transmitting packets in multiple portions, each having a different pulse repetition frequency (PRF). Methods are also disclosed for transmitting packets discontinuously.

Disclosed are techniques for wireless sensing. In an aspect, a sensing node receives, from a sensing entity, a configuration of one or more sensing reference signal resources for a sensing session, wherein the configuration indicates a staggering pattern of a plurality of staggers of the one or more sensing reference signal resources across a plurality of time intervals, a plurality of frequency intervals, or both, and wherein each of the plurality of staggers includes one or more repetitions of the one or more sensing reference signal resources, and transmits or receives the one or more sensing reference signal resources according to the staggering pattern.

A new measurement approach is disclosed that facilitates significantly smaller size, weight, and power (SWaP) spaceborne radar systems that can provide wide swath, high resolution observations. Multiple beams employed in the scan and the complex volume and/or surface backscatter signals of each beam is recorded. Each beam is electronically swept in azimuth where each beam is held at a constant incidence angle over the azimuth sector that covers the swath. Once the sweep is complete, the platform moves forward, by one along track pixel, and the sweep is repeated in order to provide continuous mapping of the volume and surface covered by the swath. Complex volume backscatter is recorded and mapped to each altitude layer to provide full mapping of the atmosphere.
