Abstract


Stealth targets on the radar poses a great threat . The use of the polarization characteristics of the frequency resonance characteristics is an important breakthrough in anti-stealth capability to improve the modern radar . In this paper, a pre-research project to conduct in-depth research on a number of issues in the polarization VHF radar anti-stealth . Firstly, the polarization characteristics of radar target ; shrinking for several stealth targets than the model difficult to measure the low frequency band RCS analysis of the frequency range of 50MHz to 300MHz RCS test method , HH , HV , VV , VH four polarization case the low frequency band RCS test results to verify the stealth targets exist in the meter band resonance effect . Polarimetric VHF radar , according to the polarization characteristics of stealth targets , comprehensive utilization of a variety of polarization information processing method and resonance effect to the purpose of anti-stealth radar . Different polarization characteristics for interference studies using a variety of polarization filter anti-jamming ; polarimetric mode , select adaptive polarization matched filter detection , the use of multiple polarization channels stealth target detection ; for the frequency sensitivity of the meter band stealth targets proposed full-band frequency preferred way to improve the ability of the radar to detect stealth targets . Through the the RCS measured data and computer simulation results show that the work of this paper .
