Daisy – Development of low-cost radar sensor technology
Sensors play an ever increasing role in modern society: the increasing number of incidents with drones flying in the vicinity of airports is a good example of the necessity of high-performance sensor technology. An Active Electronically Scanned Array (AESA) radar is the sensor of choice in the high-end security (defence) segment; however, the cost level of these sensors typically prohibits their use for other applications. The Daisy concept realizes a breakthrough in reducing the cost level of AESA sensors, making a wide spectrum of applications possible.
The main cost driver of the AESA sensor is the transmit/receive module. Daisy reduces this cost level through very high integration of the electronics: the complete module is integrated into a single component, comparable to a Lego brick. This results in a cost reduction of a factor of 10 compared to the current state of the art. Additionally, the volume of the sensor is reduced by a factor of 25, resulting in a thickness of only 2 cm. A step that can be compared to the transition from the ‘classical’ television to the LCD TV. In the Daisy project this concept has been realized, resulting in a functioning demonstrator.
