With CAAP the jammer cancellation can be done with dramatically less processing, with orders of magnitude fewer training samples and with less degradation of the antenna sidelobes. With digital beam forming (DBF) now being more widely used CAAP becomes more feasible to implement. Its time has come. It should be looked at. The results are presented in tutorial form without heavy math. Instead physical explanations are given for these results. The CAAP technique makes use of the information available as to where the jammers are rather than assuming their location is not known as done for the classical sample matrix inversion (SMI) method. This is reminiscent of the Knowledge Aided-STAP (KA-STAP) technique used by DARPA. In many cases no interference covariance matrix inversion is needed and when needed the matrix size is reduced by orders of magnitude and in turn the computation of its matrix inverse. This method reduces the 10 to 30 dB antenna sidelobe degradation usually resulting from using the SMI method. The advantages re the use of diagonal loading (DL) and the principal component (PC) techniques are also addressed. The CAAP technique lends itself well to conventional and MIMO array systems when digital beam forming is used which is the future trend.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130866517","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 Active Antenna Array Unit of modern Active Phased Array Radars consists of Radiating elements, Transmit/Receive (T/R) Modules and associated RF & Digital electronics. This paper explores the existing technologies and suggests improvements for the development of futuristic Active Phased Array Radars. FPGA based T/R Module Controller (TRMC) interfaces with the higher level controller over the Low Voltage Differential Signaling. The TRMC which controls $T$/R module is internally divided into three major sub blocks namely the Universal Asynchronous Receiver/Transmitter (UART) logic, Decoding logic and Control logic. The controller also provides real time status of critical components of the T/R Module, such as DC power supply temperature, forward power monitoring, reverse power monitoring etc. In proposed architecture we have used suitable Xilinx FPGA and achieved a switching time of <50ns. The realized unit has improved efficiency, reliability and compact without compromising the electrical parameters of T/R Module functionalities. Modern long range Active Array Radar systems are built with large number of solid state T/R Modules for realization of high power aperture product. These radars with multi-function capability require faster target update rates as well as low side lobe levels. For realization of large power aperture multiple T/R Modules are packaged in a single housing. The electronic scanning as well as low side lobe levels are achieved by controlling phase and amplitude of T/R Modules distributed in Active phased Array Radars. As a part of research, several TRMs have been realized, tested, qualified and integrated successfully with the Active Phased Array Radar.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130948311","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}

Unlike traditional beam-scanning technology, this paper $mathbf{p}$ roposes a new approach for transient radio target detection using focal-field feature matching. As for traditional phased array feed (PAF) telescope with few array elements, the features of focal-field distribution (FFD) are very limited. Exploiting the strong fitting ability of the neural networks, a generative adversarial networks (GANs)-based method is presented to reconstruct FFD features. Moreover, according to the abundant frequency characteristic of the FRBs, a multiple-frequency joint estimation is used to constrain the reconstruction. A shrunken Five-hundred-meter Aperture Spherical radio Telescope (FAST) model is utilized to verify the effectiveness of the method. The simulation results demonstrate that this approach can reconstruct the FFD effectively only using limited feeds and relative accurately estimate the transient position.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114368954","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}
