X-band radars provide enhanced angular resolution at a fraction of the aperture size compared to larger, lower frequency systems. Because of their low cost and small form factor, these radars can now be integrated into more research and commercial applications. This paper presents the research activities currently underway using a low-cost, X-band (9.41 GHz) Phase-Tilt Radar. The “phase-tilt” design is a novel architecture that allows for rapid electronic scanning in azimuth and mechanical tilting in elevation, as a compromise between cost and performance. This paper presents the relevant background information on the technology, as well as some initial studies and field work on the research activities performed.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121576507","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}

A significant component of the signal energy arises from the blade flashes and this can be detected and extracted from the time-domain data to form an image. The method proposed for achieving this is based upon the use of a signal model corresponding to the structural components of a blade, a form of the matched filter, a `matching pursuit' representation, and a form of the CLEAN technique. From this an image of a rotating blade can be synthesised, while the coefficients in the matching pursuit representation may be used for effective target classification. In this paper we demonstrate the techniques on data collected from rotating helicopter blades.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127768516","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}

If the correlation is not accounted for in a radar model, the required signal to interference ratio for a given probability of detection, Pd, could be incorrect by several dB, resulting in over-estimated performance. This paper describes a robust method for calculating the Pd for K, KK and Pareto compound distributions. Results are then presented using realistic parameter models for high grazing angle sea-clutter.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122516921","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}

The system under the test collects the beat signal from the arbitrary waveform generator, instead from the radio frequency (RF) frontend, and produces the image. Beat waveforms are prepared previously in a SAR simulator and may correspond to a variety of mission scenarios - from single scatterers and linear platform movement to complex urban scenes and perturbed trajectories of the radar carrier. With such approach the digital and software part of the SAR processor can be examined very simply and efficiently at system level.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122836392","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}

Earlier radar designs used an off-the-shelf log-periodic wideband antenna that is significantly easier to match over the SuperDARN frequency band, but expensive to buy and mount, and had limited capability for azimuthal beamforming. The newer TTFD antenna, used in many recent SuperDARN radars, offers improvement in these areas, but is in essence a narrow band antenna. It is capable of wideband operation at the cost of being difficult to match, frequency dependant, high-impedance and complex load. Previous TTFD matching transformers utilising toroids have been measured and evaluated for their suitability for the Buckland Park radar. A new system based on an LC matching network circuit has been devised to replace them. The design approach and results of the new matching circuit are detailed.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129113029","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}

The “taudot” parameter and the coupling of different echoic flow fields define interception performance. The manner in which tau-dot allows a deterministic implementation of the perception-action cycle is presented. Several simulated examples are provided demonstrating different approaches that may be take to intercept a stationary target. An analysis is provided to show that at least 24 dB of SNR is required for target interception to be reliable when using echoic flow. However, pulse integration is shown to improve this situation. Lastly a simulated example is provided that demonstrate how an accelerating target can also be intercepted without changing the underlying processing.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130680782","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}
