前不久NASA的5枚探空火箭携带示踪剂研究高空急流的实验,EODAS蹭机会试验了一下,F35的APG81雷达也参与了,两台设备装在试验机上。视频中好像黄色的是雷达跟踪的标记,紫色的是EODAS的标记,那四个圈不知道是什么意思

Northrop Grumman's F-35 DAS and Radar Demonstrate Ability to Detect, Track, Target Ballistic Missile

LINTHICUM, Md., June 26, 2012 (GLOBE NEWSWIRE) -- Northrop Grumman Corporation (NYSE:NOC) recently demonstrated the ballistic missile detection, tracking and targeting capabilities of the company's AN/AAQ-37 distributed aperture system (DAS) and AN/APG-81 active electronically scanned array (AESA) radar, both of which are featured on the F-35 Joint Strike Fighter (JSF) aircraft.

A video accompanying this release is available on YouTube at http://youtu.be/qF29GBSpRF4.

Leveraging NASA's Science Mission Directorate-sponsored Anomalous Transport Rocket Experiment launch operation, the demonstration was coordinated with NASA and the U.S. Air Force to ensure that it did not impact NASA's primary science mission goals. The systems were demonstrated in flight onboard the company's BAC1-11 testbed aircraft.

Northrop Grumman's DAS and APG-81 autonomously detected, tracked and targeted multiple, simultaneous ballistic rockets. The DAS autonomously detected all five rockets, launched in rapid succession, and tracked them from initial launch well past the second stage burnout.

"Northrop Grumman demonstrated these ballistic missile tracking modes with only minor modifications to the baseline F-35 JSF radar and DAS software," said Jeff Leavitt, vice president of Northrop Grumman's combat avionic systems business unit. "Since DAS is always staring simultaneously in every direction, an operator does not have to point the sensor in the direction of a target to gain a track. The F-35 pilot could continue the primary mission while the sensors automatically observe ballistic missile threats."

The APG-81 AESA radar demonstrated the ability to provide acquisition and weapons quality tracks independently, and also via pointing cues from DAS for expedited and extended range target acquisition. The radar maintained each track from initial acquisition until the rocket exited the radar's field of view.

Leavitt added that Northrop Grumman is currently exploring how the existing DAS technology could assist in several additional mission areas, including irregular warfare operations.

The multifunction AN/APG-81 AESA radar is capable of the full range of air-to-air and air-to-surface capabilities complemented by significant electronic warfare and intelligence, surveillance and reconnaissance functions. The AN/AAQ-37 DAS provides passive spherical awareness for the F-35, simultaneously detecting and tracking aircraft and missiles in every direction, and providing visual imagery for day/night navigation and targeting purposes.

看这视频,雷达还是很牛的。
这种实验不知道我们有没有
刷了半天还是看不到。。。。算了吧。。。。。。。
应该跟平衍的瞄准一样, 一个是目标指示,一个是锁定框
从视频来看,EODAS跟踪第一枚火箭跟得很好,第二枚以后就不行了

第二枚DODAS歪的离谱

注意黄框里面也有紫圈,下面的紫圈是一级助推器。
立刻就想起df21d了,有没有机会拦截下来?

这个真没看到
为啥不打下来呢
追的准是正常的,火箭发动机的温度那么高,要是这都追踪不准那F35的EODAS玩蛋去得了
为什么看不到
貌似很牛的样子!可以当前期导弹预警用了。。。!

此言差矣!

很简单的道理:距离远了的话,温度再高也很难追踪,距离近的话,温度再低,也很难不被探测到。

所以,我关注的是这个是在多远距离上追踪到的。

貌似以前的报道是可以追踪120里外的火箭,xx里外开加力的f16~
F35是绕圈飞的,从视频可以看出,镜头往前移动,然后往右移动。
但是我们看到的画面确很稳定,EODAS环绕飞机四周的镜头提供了没有死角的红外数据,不论飞行员怎么飞,某个方向的数据还是那么稳定。咱们家的20希望也能这样。
多探头图像合成和移动光点跟踪都不是什么很难的事,家里电脑上拿普通网络摄像机写两行程序都能搞,这技术难处是那高分辨率红外探头和能实时处理高带宽图像的处理器,兔子红外探头棍B和筷B上都见过了,高速DSP或FPGA也有国产的,所以J20或粽子上有没有类似系统只是一个需求的问题

没有那么容易。

要高像素的感光元件,也需要较大的光学镜头。这个可不是网络摄像机可以比的。

我说的是摄像头得到图像前需要好的镜头,否则高分辨率也打折扣。可到摄影发烧友的论坛去了解。

红外镜我见过,承认不懂,不过摄影爱好者也不会有人能接触那东西
家里随便写程序玩的话,我用640x480的普通网络摄像头从阳台上就能识别2像素大小的移动目标,没有任何特殊镜头,有兴趣可以去科普以下相位相关和对数极坐标映射
哦,还有光流分析,我比较喜欢Horn–Schunck算法

用数学可以算出来什么分辨率可以识别多远处的东西。用三角函数。

呃,确实是,我看的视频太小了,看不到黄圈里的紫色
F35能够探测洲际弹道导弹?
2012-6-28 09:39 上传

这个能探测飞机吗?
如果能自动探测和跟踪对方飞机,F35在格斗空战中就太占优势了。

这设备是F35用的,但这次不是装在F35上,而是装在别的试验机上。
全向跟踪,结合全自动的自卫系统,被中程弹或近红外弹追压力大减啊
要是火箭飞的比本机高就得翻180度倒着飞了吧

主要是针对上升段的,飞的更高就要向DSP之类的卫星交班了

第三枚刚发射后不久,确实跟丢过2,3秒,但是雷达始终探测到
不过已经很厉害了

你可以看一下29楼的火箭,第三枚也是两级的;一级助推器熄火后DAS显然会失去目标;二级点火后DAS立刻又锁定到了目标。这不能算“跟丢”,毕竟DAS探测的是热信号。
科普贴。。。

DSP卫星当初设计时就有针对上升段的洲际弹吧,指望战机先于卫星探测到再交班有点多余.让战机具备探测能力怎么看都像是针对诸如TG,波斯北棒的大量中短弹尤其是希望让空中的35能自行搜索并尽快赶到消灭发射车.
没有看到距离有多远啊
