Alternately, by reciprocity, the receiver could be buried in close proximity to a suspected target using ground contact or airborne transmitters. The ultimate goal of this project is a stand-off capability using satellite communication links. The received signal could also be relayed to a surface repeater by deploying a fiber-optics cable during earth penetration.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115400660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such an approach requires at least one more diversity domain to ensure that the different signals can be separated at each individual receiver; otherwise it reduces to transmit beamforming. This paper investigates the specific case where two separated transmitters transmit two signals with the same frequency band and bandwidth, but with different modulation (up-chirp and down-chirp LFM). An approach based on a Kalman filter (KF) is described herein, and results obtained by processing simulated data are compared to results obtained using a conventional matched filter (MF). The results indicate that the KF provides improved pulse compression accuracy over the MF in the range of cases considered herein. Additionally, the KF estimates the complex phase and the magnitude better than the MF. For applications where phase history is important, the KF seems to have an advantage.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122148033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forward scattering systems are in principle easy to construct. This paper shows a realization of a forward and back scattering radar system carried out by Forsvarets forskningsinstitutt for the purpose of generating both ISAR signatures of ships simultaneously. Forward scattering can give significant enhancement due to Babinet's principle. The processed results show that forward scattering and backscattering ISAR give different ship signatures, and can, when combined, give increased ability for ship classification, recognition and identification.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":" 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120827986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An eigendecomposition of the interference plus noise covariance matrix may be used to construct such waveforms as well as the multistage Wiener filter. These waveforms may have nonwhite (colored) noise spectra and have unique interference mitigation properties. An ambiguity function analysis is presented for colored waveforms to illustrate: 1) ambiguities, 2) resolution/accuracy of range (time) and Doppler (frequency) estimates, and 3) inherent interference rejection capabilities. Waveform performance is parameterized by metrics such as interference rank and others.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132412784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
