The front camera detects the obstacle and the evaluation algorithm connected to it sounds the alarm. It classifies the branch as a hazard and initiates braking. At the same time, it reports the position and the type of obstacle to a cloud server using the mobile network.

WebJun 3, 2016 · The main objective of this paper is to detect a target in marine RADAR by persevering constant false alarm rate using first order and second order microwave differentiators. In existing detection, conventional differentiators, which are made with R & C components were used. By using this RC differentiator, the display system of the target … WebFast Time Constant (FTC) circuit - Reduces clutter by displaying only the leading edge of the echo returns. Sensitivity Time Control (STC) circuit - Reduces receiver gain at close-in ranges where clutter is strong, while allowing a gradual return to normal gain at longer ranges where clutter is less. linksys customer service number
