"Compared with the centimeter-band radar with the highest accuracy, stealth combat effectiveness is only hard to find. If you want to move out of the World War II antique Mibo radar, you can give it to. Although the technical origin of meter-wave radar is relatively early, it is not possible to judge the advanced and backward radar by the wavelength of radar wave.

The reason why meter-wave radar can detect stealth aircraft is that the thickness of the coating of absorbing material used by stealth aircraft can only play a stealth role when it reaches a quarter to a tenth of the radar wavelength, and meter-wave radar has a long wavelength, so it is impossible to absorb meter-wave on the aircraft.

Secondly, because the wavelength of the meter-wave radar can be compared with the geometric size of the aircraft, the aircraft with stealth design can still be effectively detected by the meter-wave radar. For those radars with centimeter wavelength, the RCS radar cross-sectional area is about 0. 1 m2, and the RCS radar cross-sectional area is about 1 m2.

However, the early meter-wave radar also has great limitations, such as the defects caused by wavelength physical characteristics such as fast beam attenuation, poor long-distance detection accuracy and long detection period.
