Here is why our radar system
is so unique.
A key requirement in the various applications of our radar, is the need for detection of very small targets.
In particular detecting projectiles in the target scoring application and small foreign object debris (FOD) in the airport safety application, poses significant challenges for a radar system.
To provide detection capability against such small objects, our radar will therefore be operating in the Ka-frequency band(approximately 35 GHz) in which the wavelength of the radar signal is approximately 1 cm.
This is due to the fact that the ability to detect a target diminishes when target dimensions are comparable to the wavelength.
So, using a lower operating frequency with a longer wavelength would mean we could not detect such small targets like projectiles used in aircraft. In comparison many radars operate in the X-band where the wavelength is approximately 3 cm.
So even though it is more complicated to design and build a radar in the Ka band frequency, we have chosen to do so due to the obvious advantages it provides in the performance of the radar system.
Separate antennas
Our radar system utilizes separate transmit and receive antennas.
This provides for a very high isolation between the transmitted and the received signal, which is not possible when utilizing a combined transmit and receive antenna.
Without this isolation, it becomes very difficult to detect weak return signals stemming from small targets. Both antennas are based on an innovative very low-loss slotted waveguide (SWG) array design with inherent beam steering capability and support of multiple beams.
Monopulse Accuracy and Wide Area Coverage
The receive antenna supports monopulse operation, enabling precise angle-of-arrival estimation for accurate target localization. Coupled with the use of multiple, narrow beams, this allows the radar to maintain high spatial resolution across a wide field of view.
This configuration is especially beneficial in scoring applications, where the radar can detect and localize impact points of projectiles—even those that deviate significantly from the target center.
True 3D Tracking Capability
Our radar system can steer its beams in both azimuth and elevation, allowing for accurate 3D localization of targets.
Adding a Fourth Dimension: Velocity
Beyond position tracking, the radar also processes Doppler frequency shifts by transmitting multiple waveforms and analyzing the return signals. This enables accurate velocity measurement, effectively making it a 4D radar system.
This Doppler capability allows the system to differentiate between moving and stationary objects, and even distinguish between different types of moving targets—such as birds versus drones—based on their unique velocity profiles.
