Class D Amplifier For Active Sonar Systems

Defence and Military Sensors

Over the years the sensor industry has been a major supplier to the defence sector. Australia and the United Kingdom have led the way in innovation and technology. Our parent company Semefab started producing sensors in 1982 and since then we have supplied over 50 million sensor dies.

Examples of our sensors and MEMS for defensive capabilities are as follows:

1. Radar Sensors

By transmitting pulses and capturing the reflection of radio waves, radar sensors have been used since the second world war. Developed by Sir Robert Alexander Watson-Watt in the UK in 1935 , can detect and track aircraft, missiles, ships, and ground vehicles. Applications include air defense systems, missile guidance, and perimeter security. For example, ground-based radar systems can provide early warning for incoming missiles.
 

2. Infrared Sensors

Our range of eye-like visible response sensors includes both dawn/dusk sensors and daylight sensors that can be used in a variety of applications including: identifying vehicles, equipment, or personnel easier. This technology is frequently used for surveillance, night vision, and targeting systems, such as thermal imaging cameras in uncrewed aerial vehicles.
 

3. Acoustic Sensors

Acoustic sensors or we class under our MEMS products capture sound waves to
help detect potential enemy threats. This is particularly useful in active military
operations, where the goal is to distinguish among conflicting sounds from aircraft or
drones and determine threat levels.
 

4. Quantum Sensing

Quantum sensing is an advanced technology that leverages the unique properties of quantum mechanics to measure physical quantities with unprecedented sensitivity and precision. Quantum sensors can detect extremely small changes in magnetic fields, temperature, acceleration, pressure, electric fields, or other physical parameters, making them ideal for applications where conventional sensors fall short. These sensors exploit phenomena such as quantum superposition, entanglement, and coherence to enhance their capabilities beyond classical limits, enabling measurements that were once thought impossible.
 

5. Lidar Sensors

Light detection and ranging L.D.I.R uses lasers rather than radio waves found in radar units to measure distances and map environments. Applications include battlefield mapping, determining line of sight, aiding in mine countermeasures and the autonomous navigation of military vehicles.
