1. Missile guidance: One of the main uses of millimeter-wave radar is the terminal guidance of tactical missiles. The millimeter waveguide seeker has the characteristics of small size, low voltage and full solid state, which can meet the requirements of the bomb-borne environment. When the operating frequency is selected at 35 GHz or 94 GHz, the antenna aperture is generally 10-20 cm. In addition, millimeter-wave radars are also used in beam guidance systems to control short-range missiles.
2. Target surveillance and interception: Millimeter wave radar is suitable for short-range, high-resolution target surveillance and target interception, and is used to monitor low-altitude flying targets, ground targets and outer space targets.

3. Artillery fire control and tracking: Millimeter wave radar can be used for artillery fire control and tracking of low-altitude targets. It has been developed into a 94 GHz monopulse tracking radar.

4. Radar measurement: High-resolution and high-precision millimeter-wave radar can be used to measure the characteristics of targets and clutter. This kind of radar generally has multiple operating frequencies, multiple receiving and transmitting polarization forms, and variable signal waveforms. The radar cross-sectional area of ​​the target is measured using the frequency ratio method. Using millimeter-wave radar to measure the scaled down target model, the cross-sectional area of ​​the radar target at a lower frequency can be obtained.

In addition, millimeter-wave radars are also used in terrain tracking, missile fuzes, and marine navigation.
