Radar that works between the frequencies of 8.0 and 12 GHz is known as X-band radar.

The global X-band radar market is estimated to account for US$ 5,122.5 Mn in 2018 and is expected to grow at a CAGR of 3.8% during the forecasted period (2019–2027). In other words, The X-band radar is a kind of radar that operates at frequencies between 8.0 and 12 GHz.


The X-band refers to a frequency range in the electromagnetic spectrum and microwave radio spectrum. These radars are widely employed in a variety of industries since they may be mounted on smaller antennas on boats and land to improve target detection. Mobile X-band radar and sea-based X-band radar are the two types of X-band radar available. In most cases, a sea-based X-band radar is deployed on a man-made tower in the water.


X-band radar is also self-propelled and is commonly utilised in ballistic missile defence systems.

Marine radar pictures identify not just hard objects like ships and coastlines, but also’sea clutter,’ which is reflections off the water surface. Backscatter from the sea surface becomes noticeable in radar pictures when the wind speed exceeds around 3 m/s.


The resonance between the radar waves and the objects on the sea surface is the main cause of such wave reflections (Bragg Scatter). Only extremely brief water waves reflect the radar signals since the radar wave length is in the centimetre range. Longer waves, on the other hand, alter the base signal (the extremely short waves).


The primary drawbacks of X-band radar are its restricted range and the necessity for enough sea debris (and hence substantial wave height) to image the waves. Due to the restricted range of X-band radar, either a permanent platform or a vessel would have to be deployed quite near to the region of interest.


The requirement for a fixed offshore platform would negate some of X-band radar’s natural benefits as a remote-sensing technology, such as simplicity of installation and onshore maintenance, and would result in a significant increase in cost. Rainfall interference is also a problem for X-band radar systems, which is why weather radars employ this frequency to detect rainfall.
