Radar cloaking apparatus and methods of use

A radar cloaking apparatus configured for positioning on a radar target defining one or more scattering features, the radar cloaking apparatus comprising:

• a first polarization channel receiving antenna configured to generate a first channel electrical signal in response to an interrogation signal being incident thereon;
• a second polarization channel receiving antenna configured to generate a second channel electrical signal in response to the interrogation signal being incident thereon;
• first polarization receiving circuitry configured to process the first channel electrical signal to generate a first channel extracted information signal;
• second polarization receiving circuitry configured to process the second channel electrical signal to generate a second channel extracted information signal;
• first polarization emitting circuitry configured to process a first portion of the first channel extracted information signal and a first portion of the second channel extracted information signal to generate a first channel emission signal;
• second polarization emitting circuitry configured to process a second portion of the first channel extracted information signal and a second portion of the second channel extracted information signal to generate a second channel emission signal;
• a first polarization channel emitting antenna configured to transmit a first channel cloaking radio signal based on the first channel emission signal;
• and
• a second polarization channel emitting antenna configured to transmit a second channel cloaking radio signal based on the second channel emission signal.
