<http://dbpedia.org/resource/Secondary_surveillance_radar>	<http://dbpedia.org/ontology/abstract>	"Secondary surveillance radar (SSR) is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with a radar transponder, that reply to each interrogation signal by transmitting encoded data such as an identity code, the aircraft's altitude and further information depending on its chosen mode. SSR is based on the military identification friend or foe (IFF) technology originally developed during World War II, therefore the two systems are still compatible. Monopulse secondary surveillance radar (MSSR), Mode S, TCAS and ADS-B are similar modern methods of secondary surveillance."@en .

Pancaran radar ini berupa pulsa-pulsa mode, pesawat yang dipasangi transponder, akan menerima pulsa-pulsa tersebut dan akan menjawab berupa pulsa-pulsa code ke sistem penerima radar. Stasiun Radar SSR yang berada di bawah (Ground Station SSR) terdiri dari Transmitter (Tx), Receiver (Rx), Processing atau Extractor Video, Coder, dan Monitor / Plane Position Indicator. Transmitter bekerja pada frequensi carrier 1030 MHz yang dimodulasi oleh sinyal Mode A dan Mode C. Pada dasarnya Transmitter ini seolah-olah berfungsi sebagai alat pengirim sinyal penanya, yang lazim"@in .

SSR is based on the military identification friend or foe (IFF) technology originally developed during World War II, therefore the two systems are still compatible. Monopulse secondary surveillance radar (MSSR), Mode S, TCAS and ADS-B are similar modern methods of secondary surveillance."@en .

<http://dbpedia.org/resource/Secondary_surveillance_radar>	<http://dbpedia.org/ontology/abstract>	"Secondary Surveillance Radar (SSR) merupakan sebuah peralatan untuk mendeteksi dan mengetahui posisi dan data target yang ada di sekelilingnya secara aktif, dimana pesawat ikut aktif jika menerima pancaran sinyal RF radar sekunder. Pancaran radar ini berupa pulsa-pulsa mode, pesawat yang dipasangi transponder, akan menerima pulsa-pulsa tersebut dan akan menjawab berupa pulsa-pulsa code ke sistem penerima radar. Stasiun Radar SSR yang berada di bawah (Ground Station SSR) terdiri dari Transmitter (Tx), Receiver (Rx), Processing atau Extractor Video, Coder, dan Monitor / Plane Position Indicator. Transmitter bekerja pada frequensi carrier 1030 MHz yang dimodulasi oleh sinyal Mode A dan Mode C. Pada dasarnya Transmitter ini seolah-olah berfungsi sebagai alat pengirim sinyal penanya, yang lazim disebut sebagai \"interogate signal\". Bilamana \"interogate signal\" ini dimodulasikan dengan \"mode A\", berarti pemancar atau interogator mengirim pertanyaan tentang identifikasi pesawat (aircraft identification), dan bilamana interogator mengirim mode C berarti mengirim sinyal pertanyaan tentang ketinggian (altitude) pesawat. Mode A atau mode C dikirim oleh interogator secara interlacing (bergantian) setiap PRT ( pulse repetition time), umumnya PRF radar SSR adalah 450 Hz, jadi PRT = 1/450 detik = 2,22 mdetik. Receiver menerima sinyal jawaban dari transponder pesawat dengan frequensi 1090 MHz. Manakala interogator mengirim mode A yang dimodulasi dengan frequensi carrier sebesar 1030 MHz, maka transponder di pesawat akan menerima sinyal ini dan akan dikirim kembali oleh transponder (reply signal) yang berupa sinyal kode (code signal) dan dimodulasikan dengan sinyal carrier transponder sebesar 1090 MHz, sinyal kode ini nantinya diolah pada bagian Extractor Video dan seterusnya ditampilkan pada layar monitor berbentuk identifikasi pesawat, begitu pula apabila interogator mengirim mode C, informasi yang ditampilkan dilayar monitor adalah \"ketinggian pesawat\". Sesungguhnya radar SSR dapat mendeteksi asimuth (koordinat) pesawat, jarak pesawat terhadap SSR Station dan kecepatan pesawat, disamping identifikasi dan ketinggian pesawat \""@in .
