Processing chain of a radar network for safety improvement in the usage of heavy machinery

Abstract

The use of heavy machinery is one of the main causes of accidents in sites as warehouses or construction. These vehicles have several blind spots that encumber their maneuvering and create a collision-prone environment. To ensure safety in these situations, an early warning system capable of avoiding these accidents is required. An innovative solution consists of the use of a on-board, low-cost, K-band radar network. The complete system is to operate with a very low false alarm rate (FAR) to avoid unnecessary stops and loss of trust by the driver. In order to fulfill this requirement, a processing chain that rejects false detections is implemented. It is also responsible for joining data from all the subsystems of the network.
