Low Cost, Low Power 24GHz Radar Sensor

Abstract/Technology Overview

Currently, drones cannot operate ’beyond the line of sight’, however for drone technology to truly advance societies, economies and innovations, it is widely recognised that drone operation when they can be directly seen by the operator, is necessary.

Whilst Light Detection and Ranging and video streaming are answering some of the positional and navigational problems experienced by drones and robotics, they have limited performance over long ranges and low light/visibility.  Radar sensors, however, offer a viable route for drone operation beyond the line of sight, provided their traditional constraints of cost and weight can be overcome. 

Radar is traditionally bulky, costly and contains moving parts. With advances in the new technology radar, these barriers to market for equipment which require mobility such as drones and robotics are now significantly reduced.

Slipstream Engineering Design’s approach to addressing the need for lower cost, aerodynamic, lightweight radar sensors for drone and robotic integration is the production of a radar Transmit-Receive Module which operates at 24GHz that builds on RF devices and microelectronic technologies developed for the telecommunications and automotive markets. 

Slipstream Engineering Design is developing a miniaturised 24GHz radar Transit Receive Module with a 360-degree field of view which will be a significant innovation within the drone and robotic sensor market. The radar Transit Receive Module is designed to be a compact, power conserving and cost sensitive format thus making it ideal for drone and robotic applications. 

Technology Features, Specifications and Advantages

Slipstream Engineering Design’s miniaturised 24GHz radar Transit Receive Module addresses the need for a lower cost, aerodynamic, lightweight radar sensor for drone and robotic integration. 

The radar Transmit-Receive Module operates at 24GHz and builds on RF devices and microelectronic technologies developed for the telecommunications and automotive markets.  The resulting technology has a 360-degree field of view, giving a significant advantage to detect objects in all directions. 

Coupled with RF beam steering by passive means to focus RF gain, the power efficient sensor will also offer enhanced detection of objects at distance.


  • 360-degree field of view 
  • Integrated passive beam steering technology for increased RF gain
  • Reduced processing time
  • Reduced power consumption, weight and size
  • Reduced cost

Potential Applications

An increasingly complex drone ecosystem requires drone hardware companies to seek a point of product differentiation. Drone suppliers can stand apart from their competitors and gain market share by employing quality "sensory perception" as part of their UAV, enabling safe flight and also rationalising deployment costs.  A miniaturised 24GHz radar with a 360-degree field of view offers a significant innovation within the drone sensor market. 

Slipstream Engineering Design believes that the miniaturised radar sensor technology has multiple applications across a variety of markets:

  •  Presence and motion detection
    • Lighting
    • Home automation
    • Surveillance
    • Industrial robotics
  • Speed and velocity detection
    • Consumer and leisure applications such as sport tracking
    • Industrial instrumentation
    • Industrial robotics
    • Autonomous vehicles
