SharpEye™ Doppler radar has found applications in providing risk mitigation data to organisations. By being able to conduct surveillance of an area and recording movement of objects from the radar tracks, it is possible to build up a picture of time of the activity of a wide open area.

A good example of how this technique has benefited wildlife and human habitats is the placement of a renewable energy facility in an area known to be inhabited by certain wild animal species. The area planned for this new facility was located in a place where the animals were known to occupy during the seasons of migration. For a few months of each year it was known where the animals would leave from and ultimately arrive at, butit was not known what routes they would take so obviously disturbing the habitat by a large industrial installation could have disastrous effects.

Radar track data was collected over a 12 month period using a SharpEye™ radar system that enabled accurate migratory information to be compiled and this was used to help influence a suitable location and design for the facility.

SharpEye™ transmits a low power patented pulse sequence, which enables short, medium and long range radar returns to be detected simultaneously.

Doppler processing of radar returns provide coherent information concerning target's velocity (radial) and enables the detection of very small and slow moving objects and targets with a low Radar Cross Section (RCS) and through a series of electronic filters is able to distinguish between the targets of interest and sea, rain and land clutter.

Other differentiating technologies include Moving Target Detection (MTD), providing enhanced clutter suppression at the Doppler processing stage and pulse compression of the return signal enabling a low transmit power providing efficient use of the radar. Other Doppler radars may employ less advanced techniques such as Moving Target Indication (MTI), which does not take full advantage of the radial velocity information.
