A method for identifying a road condition of a road. A piece of road condition information representing the road condition is determined using a noise level detected by at least one ultrasonic sensor of a vehicle and a bottom echo detected from a road surface in the area of the vehicle.

Systems, devices, and methods efficiently calculate optimal flight paths for protected entities given terrain data, aircraft position, flight characteristics, and positions of known threat emitters. The systems and methods execute within the mission planning timeline, and the developed processes allow users to retrieve data from the calculations to effectively place an electronic attack platform at the right place and at the right time to be effective. The calculated optimal flight paths are displayed or otherwise visualized in the mission space. Electronic attack jamming capabilities are combined with projected threat emitter performance information in order to obtain optimal geometrical positioning of the electronic attack relative to the threat emitter. Threat emitter system characteristics are combined with electronic attack aircraft capabilities while simultaneously incorporating the position of the protected entity aircraft and rendered to assist the electronic attack aircrew in providing optimal electronic attack capabilities to protect one or more entities.

Systems and methods are provided for aerostat deployable from sonobuoy launch container. One embodiment is an apparatus that includes a capsule configured to launch from an aircraft and float in seawater with one or more sonobuoys. The capsule includes a receiver configured to receive sonobuoy data from the one or more sonobuoys, a transmitter configured to transmit the sonobuoy data to the aircraft, a cable configured to power the transmitter via a battery, and a reaction chamber including a reactant and configured to generate a gas from the seawater mixing with the reactant. The capsule also includes an aerostat tethered to the capsule via the cable and configured to inflate with the gas produced by the reaction chamber, and to ascend above the capsule with the transmitter to increase a distance for transmitting the sonobuoy data to the aircraft.

An underwater acoustic deception system deceives a sensor installed on a threat existing in or on water by acoustic effect in order to protect ships from the threat. The underwater acoustic deception system is provided with a control device, a laser oscillator and emission optical system. The control device determines a focusing position to focus a laser beam (50) in water in order to generate bubbles (70) at a desired position with a desired scale and emission parameters of the laser beam (50). The laser oscillator generates the laser beam (50) configured to focus in water and generate bubbles. The emission optical system emits the generated laser beam (50) to the focusing position. The underwater acoustic deception system deceives an arbitrary sensor existing in the water by acoustic effect of the bubbles (70) on the surroundings.
