ParkSense

In June 2024, Peralex participated in the Geo-Data Fusion Hackathon organised by the Ministry of Infrastructure and Water Management and the Netherlands Space Office.

We developed ParkSense, a tool that uses deep learning to detect parked cars in satellite images and present parking density metrics to users through a web-based UI. Our solution was named runner-up in the Hackathon and was selected for further development by the ministry.

Acoustic Localisation

Peralex piloted a project to build a low-cost networked acoustic localisation system for gunshot detection. The main application of this technology is to mitigate gang violence and urban and suburban crime, but it could also be used to combat poaching of livestock and endangered wildlife.

SKA Passive Radar

The Square Kilometre Array (SKA) is an international effort to build the world’s largest radio telescope with one square kilometre of collecting area. SKA-mid is located within a radio-quiet zone in the Northern Cape of South Africa. Transmitters on aircraft are a source of radio frequency interference (RFI), which can compromise the integrity of the astronomy data.

Peralex successfully commissioned a multistatic passive radar system to monitor this sensitive area without introducing any additional RFI. Consisting of four sensor nodes, this was one of the first publicly recorded sales of a commercial passive radar system.
