  3. Huiswerkvraag Eenvliegtuigdatwordtingezetvoor stand-off jamming heefteen minimum self-screening range van 30 km. Om dezeteverbeterenwordt het vliegtuigbij de midlife modernization uitgerust met stealth techniek, waardoor het radarreflecterendoppervlak met 3dB wordtteruggebracht. • Hoeveelwordt de minimum self-screening range? • Steldatdefensiestafoverweegt, gezien de kosten van Stealth technologie, om in plaatsdaarvan het vermogen van de stoorzenderteverhogen. Met hoeveel dB moet het vermogenwordenvergrootomhetzelfde effect tebereiken?

  6. Definitie Electronic Warfare • Military action to exploit the EM-spectrum, which encompasses: • - The interception and identification of EM-emissions, • - The employment of EM-energy, including directed energy, to reduce or prevent hostile use of the EM-spectrum, • - And actions to ensure its effective use by friendly forces. • ATP 1 vol 1 pt. 5101

  7. Definitie Electronic Warfare Electronic protection (EP) • Military action to exploit the EM-spectrum, which encompasses: • - The interception and identification of EM-emissions, • - The employment of EM-energy, including directed energy, to reduce or prevent hostile use of the EM-spectrum, • ATP 1 vol 1 pt. 5101 - And actions to ensure its effective use by friendly forces.

  13. Anti ES • - EmissionPolicy (Emissie Beleid) • doel: bescherm radar parameters • doel: bescherm samenstelling eigen eenheden • middel: EMCONPLAN • - EmissionSecurity (Emissie Beveiliging) • TRANSEC: keuze LPI freq, LPI technieken (freqhopping, direct sequence technieken) • COMSEC: authenticatie, encryptedcallsigns, paper codes; on-linecrypto (secure voice, data)

  14. Anti EA • FightThrough • Technische maatregelen • Gebruik alternatieve apparatuur • Frequentie wisselen/spreiden

  20. EP techniek: radar ontwerp (Payne) • Power (airborne limitations) • Frequency (agility, Doppler: eliminate chaff) • PRF (high PRF = high power, random = anti EA) • PW (high PW = high power, but trade-off in minimum range & range resolution capability) • Antenna design (low sidelobes: anti-ES & anti-EA) • Scan pattern (random: phased array; COSRO, monopulse) • Signal processing: CFAR: Constant-False-Alarm-Rate (disadvantage: weak signals lost) • Design philosophy: incorporate unpredictability

  21. EP techniek: EA ladder (Payne) system EA EP EA EP

  22. EP techniek: Anti-EAtracking (Payne) • Tracking on receive-only: • Conical Scan On receive Only (COSRO) • Monopulse
