(Screen grab from Chinese state CCTV footage)</p><p> </p><p>MELBOURNE, Australia –<b> China is set to debut its dedicated electronic-attack aircraft</b> on public display at the upcoming Zhuhai airshow, giving observers a first look at the newly developed type.</p><p>A single example of the type, which is officially designated the<b> Shenyang J-16D</b>, has been parked at the static display area of the airshow in Guangdong Province ahead of the event, which is due to run from Sept. 28 to Oct. 3 next to the city’s airport.</p><p> </p><p>The twin-seat J-16D is based on the J-16 multirole strike fighter, which is itself a development of the J-11B interceptor and the Russian Sukhoi Su-30MK-series, both of which can trace their lineage back to the Sukhoi Su-27 Flanker interceptor.</p><p><a href="https://www.defensenews.com/flashpoints/2021/09/23/china-sends-19-fighter-jets-towards-taiwan-in-show-of-force/" target="_top" class="ke-link">China</a> has acquired the Su-30MKK and the Su-30MK2 for the People’s Liberation Army Air Force, or PLAAF, and the People’s Liberation Army Navy, PLAN, respectively. Some 70 examples of both types, which were acquired between 1996 and 2002, are believed to be still in service.</p><p>Images of the J-16D taken on the ground and posted online show that it has some notable differences from the standard J-16,<b> the most prominent of which are a pair of pods mounted on its wingtips.</b></p><p> </p><p>These are believed to perform a similar function to the Northrop-Grumman AN/ALQ-218 on the U.S. Navy’s Boeing EA-18G Growler electronic attack aircraft, which is a passive, high performance signals intelligence sensor system used for detecting, identifying, locating and analyzing sources of radio frequency emissions.</p><p>Other distinctive differences from the J-16 include a noticeably<b> shorter nose radome suggesting that a smaller radar has been fitted, along with the lack of the cannon mounted on the right side of the fuselage and the deletion of an infra-red search and track system on the front of the canopy.</b></p><p>The J-16D at Zhuhai carries the number 0109 stenciled on the side of its engine intakes, indicating that it is the ninth aircraft from the first production batch. It carries toned-down PLAAF markings but no numbers on its tail, making it impossible to identify which unit it has been assigned to.</p><p>The aircraft has also subsequently been fitted for the airshow with four of what appears to be at least three distinct types of standoff jammer pods on external stores hardpoints below both engine intakes and wings.</p><p> </p><p>Neither of these indigenously developed pods have been seen before with their designation and differences unknown, although it is likely they are for jamming different bands of the electronic spectrum.</p><p>A Chinese defense ministry spokesperson has confirmed that other new aircraft types will make their debut at this year’s show, which has been delayed from its original date of November 2020 due to the pandemic.</p><p>The other debutants will include the WZ-7 jet-powered high altitude unmanned aircraft, while China’s J-20 stealth fighter will also make an appearance.</p>

미국해군의 Electronic Warfare and Radar Systems - Engineering Handbook 2013년 판의 내용을 보면 스탠드-오프 재머는 적 레이다로부터 지켜줘야 하는 공격기와 같은 축선에 있다면 적 레이다의 main lobe를 재밍하지만 떨어져 있다면 side lobe를 재밍하고,
요즘 레이다는 side lobe를 되도록 줄이는 여러 기법을 쓰기 때문에 재밍할 레이다에 대한 정보가 필요하다고 나옵니다.
"... because many modern radars employ some form of side lobe blanking or side lobe cancellation, some knowledge of the victim radar is required to predict the effectiveness of side lobe jamming. "
참고로 EA-18G같은 Stand-Off 재머가 Self Protection 재밍을 하고 있는 다른 전투기보다 적 레이다로부터 2배 멀리 있는데, 적 레이다의 main lobe보다 30 dB 낮은 side lobe를 재밍하려고 하면 main lobe에 대한 Self Protection 재밍의 경우보다 출력이 거의 4,000배가 필요하다고 하네요.
첫댓글 슈호넷보다 큰 플랫폼이라 유사한 수준의 전자장비면 더 탁월할꺼 같긴 한데 그 전자장비 수준이 어찌될지
평소에 Y-9 정보수집기가 대만, 일본, 미국, 우리의 레이다 전파를 열심히 수집하고 다니니 나름대로 threat library를 갖추고 거기에 맞는 재밍 기법들을 연구하고 있을 것입니다. 우리는 저런 ELINT 항공기가 아예 없고요...
