This paper makes use of a simple and inexpensive software-defined radio (SDR) to demonstrate the potential threats posed to wireless communication. SDR is a radio communication system where components that are traditionally implemented in hardware are being replaced via software running on computing devices. The authors make use of a simple SDR to demonstrate how local disruption to wireless communication can be easily carried out. In particular, the authors show how FM radio broadcast can be hijacked and the spoofing of GPS location signals using a single SDR on a local basis as well as how Google Maps apps on an Android phone can be fooled by the spoofed GPS data. The authors also show how an ‘autonomous' car can be re-routed via emulation with a rigged up remote control toy car. The spoofing of GPS signals is a potential threat to all GPS-based applications, especially when powerful radios are used. The security threats on GPS-based navigation especially for drones and autonomous vehicles are real.

Challenges involved in space communications across wireless channels call for new approaches to radio systems. Due to the growing need for frequency change in modern wireless systems, an adaptive radio system has the highest demand. Software-defined radios (SDR) offer this type of adaptivity as well as compatibility with other standard platforms such as USRP/GNU radio. Despite limitations of this approach due to hardware components, viable modeling and simulation as well as deployable systems are possible using this platform. This chapter presents a detailed implementation procedure for a USRP/GNU radio-based SDR communication system that can be used for practical experiments as well as an academic lab in this field. In this experiment the USRP has been configured to receive signal from a local radio station using the BasicRX model daughterboard. The programmable USRP executes Python block code implemented in the GNU Radio Companion (GRC) on Ubuntu OS.

This paper presents analyzed questions of the safety of the information transferred by the radio connection link of the Polish UAV project “Aircraft for monitoring” SAMONIT. This safety is especially important for the design and use of unmanned aerial vehicles (UAV). This paper also presents the structure of the SAMONIT communication system, security threats to the radio connection system, and possible measures to ensure secure information.

Software-defined radio (SDR) is a kind of radio communication system which attempts to place much or most of the complex signal handling involved in receivers and transmitters into the digital style. As wireless technologies become ubiquitous, SDR are gaining popularity. In this work, we introduce the SDR platform USRP with emphasizes on hardware components, signal processing procedure and the supporting software. A radio spectrum monitoring system based on USRP and LabVIEW is designed and implemented, and web publishing of the real time spectrum is realized.

<p><em>Abstrak</em> - <strong>Software Defined Radio (SDR) merupakan sistem komunikasi radio berbasis software yang saat ini mulai banyak diimplementasikan dan menunjukkan potensi yang besar. Tingginya efisiensi dalam hal biaya dibandingkan dengan sistem konvensional berbasis perangkat menjadi motivasi bagi berkembangnya konsep ini diberbagai aplikasi. Salah satu aplikasi yang dapat diterapkan menggunakan konsep SDR adalah sistem komunikasi Radar, Software Defined Radar (SDRadar). Radar berbasis software diharapkan dapat menurunkan biaya pembuatan hardware, serta dapat mendukung perancangan Radar yang dapat melakukan banyak fungsi dan lebih flexible untuk melakukan konfigurasi ulang. Radar multifungsi dapat dibangun dengan berbasis software yakni mulai dari pengaturan jenis sinyal, frekuensi operasi, hingga pada tahap pemrosesan sinyal radar. Penelitian ini merancang FMCW Radar menggunakan platform SDR.  Simulasi dilakukan dengan mencoba posisi objek yang berbeda, dengan nilai SNR yang berbeda. Hasil simulasi menunjukkan implementasi konsep SDR untuk Radar dapat mendukung fleksibilitas rekonfigurasi parameter Radar. Untuk spesifik radar yang disimulasikan diperoleh bahwa SNR yang baik untuk dapat mendeteksi jarak object dengan baik (error &lt;11%) ialah diatas 20dB. Radar dengan SNR dibawah 20 dB tidak dapat mendeteksi jarak objek dengan baik, dimana error melebihi 50%. Radar Pulsa disimulasikan menggunakan pernagkat USRP dengan factor pengkoreksi/kalibrasi 1.376, sedangkan untuk Radar FMCW masih terdapat error sebsar 70.8%.</strong></p><p><strong> </strong></p><p><strong><em>Kata Kunci : </em></strong><em>SDR, SDRadar, FMCW Radar</em></p><p><strong><em> </em></strong></p><p><em>Absract - </em><strong>Software Defined Radio (SDR) is a software-based radio communication system that is currently implemented and show great potential to be developed. The efficiency in terms of cost as compared to conventional systems which based on devices is a motivation for the development of this concept in various applications. One of the applications that can be implemented utilizing the concept of SDR is Software Defined Radar (SDRadar). Radar with software based is expected to have lower cost and support the feasibility of Radar to perform in many functions and more flexible to be reconfigured. This research implement the FMCW Radar using SDR platform. Simulations carried out by trying different object positions, with different SNR values. The simulation results show the implementation concept of SDR's Radar can support the flexibility of Radar parameter reconfiguration. For specific simulated radar shows that a suitable SNR value to detect the distance of object (error &lt;11%) is above 20dB. Radar with SNR under 20 dB could not detect the distance of objects well, where the error exceeds 50%. Radar Pulse also simulated using USRP with factor correction or calibration factor of 1,376, while for FMCW with USRP still obtain high error of about 70.8%.</strong></p><p><strong><em> </em></strong></p><p><strong><em>Keywords:</em></strong> <em>SDR, SDRadar, FMCW Radar</em>.</p>
