A hardware and -software solution for a low power consumption acoustic sensor, included into a wireless sensor network, based on ultra-wideband chaotic radio pulses is discussed. Low power consumption of the sensor is ensured by power-efficient electronic components and a new compression method PADPCM, which is resistant to data block loss during packet transmissions within sensor networks.

This paper discusses the methodology of conceptual design of the airborne radar with antenna aperture synthesis (AAS) in the framework of mathematical technology paradigm, focusing on physical, rather than phenomenological models. The performance criterions of design for AAS as a whole system and for its subsystems have been introduced. Approximation of specific effective echoing areas (SEES) matrix on remote sensing data by means of two-dimensional atomic interpolants, two-dimensional atomic Kravchenko wavelets and two-dimensional generalized Kotelnikov theorem with vector parametric atomic functions is considered. The theory of growing interfaces and the classical problem on plane electromagnetic wave diffraction on a wedge was used to build accurately solved models of electrodynamic properties of underlying surfaces in cold regions of the Earth.

The paper investigates power consumption of direct chaotic transceivers designed for wireless ultra-wideband sensor networks. Possible ways of energy saving to provide long autonomous operation period of the transmitters are proposed. To this end, several approaches are used: design solutions using low consumption electronic components, communication protocol organization reducing the load on devices, and introduction of hibernating modes.

Problems of the specific use of specialized element components to create short-range radar system on the basis of ultrashort pulses with low power consumption, based on a single-chip transceiver without the use of high-speed ADC, are discussed. The results of laboratory measurements of system parameters are presented. The possibilities for the practical use of the system as a sensor for the people detection in the protected area, a sensor for the obstacle detection in model-based vision system, a sensor for remote measurement and monitoring of human breathing and heartbeat parameters in medicine or when performing work related with an increased risk, a portable radar for the people detection behind the obstacles, or buried under the rubble of building structures, snow avalanches, and training laboratory equipment are demonstrated.
