For low resonance (low-Q) targets this is particularly vital, as the processing must be set late enough to avoid including signal data caused by early-time (non-resonant) scattering, but early enough to maximise the signal-to-noise ratio for the late-time component of the target response. Without knowledge of the target's orientation to the incident excitation, the late-time start must be determined from the signal data alone. The spectral norm of the impulse response data matrix (Hankel matrix), examined over a sliding window, provides a robust indicator of the late-time commencement.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125949327","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}

This architecture has been developed specifically for low-cost, small-scale radar applications and in dense radar networks. The electronic scanning in azimuth combined with mechanical elevation tilt allow for increased scan speed at severely reduced maintenance costs. This paper presents the calibration and preliminary data results of the Phase-Tilt Weather Radar. Measurements from a severe thunderstorm in Amherst, MA, US will be presented, along with initial calibration analysis and tests performed. Analysis of the data indicates good weather sensitivity and dual polarimetric performance, commensurate with similarsized, mechanical X-band radars.","PeriodicalId":365285,"journal":{"name":"2013 International Conference on Radar","volume":"15 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":"125655375","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}

In the direction of radiation, the antenna is followed by a dielectric cone of high-density polyethylene (HDPE), whereby the front of the cone terminates in a radial lens shape for beamforming purposes. The presented setup is designed and built for W-band (75 to 110 GHz) operation, the concept itself can also be used for any other frequency range.

The HFSWR's architecture uses multiple input, multiple output (MIMO) techniques to provide some distinct advantages in operational performance and deployment flexibility.

The network consists of several transmitters/receivers that operate on the same channel and exchange data with each other. The passive radar listens to the communication and performs decoding of captured frames, and determines the WiFi network node which was the source of the transmitted frame. The received data stream is divided, based upon the decoded source address, into data streams sent by each network node, after which the separated data streams are processed using classical Passive Coherent Localization methods in order to detect target presence and to localize detected targets.
