This book starts out strong, but it has some huge holes in out. Boyd was,
obviously, a genius. However, ... 阅读全帖 |

我找了下 MGM-31 Pershing -用的雷达资料. 你能用普通话翻译下么? 这个有啥特点?
With its Singer Kearfott inertial guidance system, and the Goodyear
Aerospace active radar terminal guidance unit in the warhead, the MGM-31C
achieved an accuracy of about 30 m (100 ft) CEP at a range of up to 1770 km
(1100 miles).
The goodyear aerospace company (RADar Area Guidance or RADAG) system was
selected for terminal navigation. It scanned the target area with J-band (ie
, 10 to 20 GHz) frequency radar during reentry, compared the image... 阅读全帖 |

F35基于错误的理论"飞机的机动性无关紧要,让导弹做转圈的活. "
* 第一, 假定F35能撑到可发射导弹的位置, 但是J20和T50拥有低可探测性, 又非得多
快得多, 因而使他们的下视下射导弹拥有先发制人的优势;
* 第二, 更危险的是, J20和T50有超强的应对来袭导弹的措施(包括超机动, 隐形等,超
高速,及电子对抗措施, 让F35会转圈的... 阅读全帖 |

find plenty of radar detectors for sale. base on my past experience, don't
get those cheap ones, under $100, cuz they are just simply worthless! worst
yet, when you have those cheap radar detector turned on in ur car, u think
u are safe, but you are not! simply b/c they are just worthless. i first
bought a $40 radar detector and got pulled over 3 times while the thing was
on.

前面3个sensor, 2个是laser defuser (图)1个是radar detector,藏在bumper后面。
后面就1个radar的，
完全built in,没任何设备在dashboard上面..
只jam laser,和detect radar但是不能jam radar
顺便猜车。。。 |

发帖数: 2045 | 47 There are radar-detector-detector-detectors.
From wikipedia LOL:
" "stealth" radar detectors were equipped with a radar-detector-detector-
detector circuit, which shuts down the main radar receiver when the detector
-detector's signal is sensed" |

detectors, themselves. However, the state does have a windshield mounting
law. Anything mounted upon the windshield is illegal. This would include
radar detectors.

发帖数: 620 | 49 那天有意外情况，在70的路上开了94.第一张罚单。会怎么罚？
当时警察和我距离0.8里相对而开，之间有很宽的隔离带。我一上坡就发现他的车有点
怪立刻刹车，还是晚了。然后，警察加速，穿过隔离带中的石子路到我这边，打警灯。
警察车不是事先停在路边，所以不可能用stationary radar，估计用moving radar测的
。听说moving radar不准，有些地方可以argue。本来想拿moving radar说说，结果警
察干脆没写用什么方法测速的。 |
