Because of the high frequency, military microwave radar has high resolution, making it suitable for detecting and tracking fast-moving and small targets with high accuracy.

• Military millimeter-wave radar

  Military millimeter-wave radar is a type of radar that operates in the millimeter-wave region of the electromagnetic spectrum, between 30 and 300 GHz. It is characterized by its high frequency, which enables precise target detection and tracking. Military millimeter-wave radar has a short wavelength, high resolution, and the ability to penetrate through various atmospheric conditions. They can be used in various military applications, including air defense, missile guidance, and target recognition.

Another military radar classification is based on mobility:

• Ground-based radar

  Ground-based radar is fixed radar deployed on the ground and used for various military applications, including air defense, surveillance, and target tracking.

• Airborne radar

  Airborne radar is radar systems integrated into aircraft, drones, and other airborne platforms. They are used for reconnaissance, target acquisition, and tracking.

• Space-based radar

  Military satellites equipped with radar systems can operate in the microwave and millimeter-wave bands. Space-based radar satellites are used for earth observation, target detection, and tracking, providing global coverage and continuous monitoring capabilities.

Specifications and maintenance of military radar

Military radar has different specifications depending on its type and use. Below are some common military radar specifications:

• Frequency range: Different military radars operate on various frequency ranges. The frequencies may differ depending on the application and radar type. For instance, L-band military radar has a frequency of 1 to 2 GHz, while the Ka-band radar has a frequency of 26.5 to 40 GHz.
• Power output: Military radar also has different power output specifications. The power output is measured in watts and indicates the strength of the radar signal. Higher power output means the radar can detect signals that are far and are weaker. For example, a military radar may have a power output of 1 to 10 watts or more.
• Antenna gain: Antenna gain is the ability of the antennas to focus the radar signal in a particular direction. Higher antenna gain means that the military radar can send and receive signals in a narrow beam and is more sensitive to the signals within the beam. Antenna gain is measured in dBi, and military radar may have a gain of 20 to 50 dBi.
• Resolution: Military radar resolution determines the ability of the radar to distinguish between different targets. The resolution is measured in time and distance. For instance, a military radar may have a range resolution of 50 m and a velocity resolution of 10 m/s.
• Tracking capability: Tracking capability refers to the ability of the radar to track different targets. Some military radars can track several targets simultaneously, while others can track a single target. The tracking capability is measured in the number of targets and can be from ten targets to hundreds of targets.
• Size and weight: Size and weight are important specifications of portable military radar. The military radars used in vehicles or ships are larger and heavier than those carried by soldiers. The military radar size is measured in centimeters, while the weight is measured in kilograms.
• Signal processing: Military radar also has different signal processing specifications. Some radars have advanced signal processing capabilities, making them more sensitive to weaker signals.

Military radar maintenance is important to ensure the effective operation of the radar and prolong its life. Below are some military radar maintenance practices:

• Visual inspection: Military radar should be inspected visually to check for any damage or wear. Things to look out for include loose connections, cracks, and damaged cables.
• Cleaning: Military radar antennas and other parts should be cleaned regularly to prevent the build-up of dirt and dust. Dirt and dust can affect the performance of the radar. A soft cloth and mild detergent should be used to clean the radar components.
• Calibration: Calibration is necessary to ensure that the military radar operates within the required specifications. The calibration should be done according to the manufacturer's instructions.
• Software updates: Military radar should have their software updated regularly. The updates improve the radar performance and fix bugs.
• Replace worn-out parts: Worn-out parts of the military radar should be replaced as soon as they are discovered. The replacement should be done according to the manufacturer's recommendations.
• Follow safety precautions: During military radar maintenance, the safety precautions recommended by the manufacturer should be adhered to.
