Problems solved by technology

Passive radar refers to the radar itself that does not emit electromagnetic wave signals but only uses target radiation electromagnetic wave signals (external radiation sources) for target detection and tracking. It has the advantages of low cost, strong concealment, and high mobility, but it will radiate to the outside world. source has certain dependencies

Abstract

The invention relates to an ultra-wideband terahertz passive anti-stealth radar. The radar comprises an ultra-wideband radiometer linear array, a focal plane ellipsoid antenna, a turntable, a servo system, a processing system and a display system. The ultra-wideband radiometer linear array receives target noise radiation and scattering, and the focal plane ellipsoidal antenna converges the targetnoise radiation and scattering received by the ultra-wideband radiometer linear array; the focal plane ellipsoidal antenna is connected with the turntable, the turntable is connected with the servo system, the servo system is connected with the processing system, and the processing system is connected with the display system. The focal plane array ellipsoidal antenna structure is adopted, a betterenergy gathering effect is achieved, and a target and noise can be better distinguished. Meanwhile, the radar power consumption can be reduced, the concealment is high, and the radar can work in a terahertz waveband.

Description

technical field [0001] The invention relates to the technical field of terahertz radar, and is an ultra-wideband terahertz passive anti-stealth radar. Background technique [0002] Stealth technology generally uses special shapes to weaken electromagnetic signal radiation in certain directions, or cover materials that can absorb radar electromagnetic waves to hide. Anti-stealth radar is a radar used to counter stealth technology and monitor stealth targets. [0003] Common anti-stealth radars include meter wave radar, dual multistatic radar, and passive radar. The working frequency band of the meter wave radar is 30-300MHz, which just avoids the stealth band (0.3-29GHz) of the stealth fighter, so it can detect the stealth fighter, but the meter wave radar has large size, poor adaptability, poor survivability, and detection accuracy Inferior problems cause its development to be limited. Dual multibase radar can achieve anti-stealth effect, but because of its activeness, it...
