间歇采样重复转发对雷达恒虚警检测性能的影响分析

作为一种新型相干干扰,间歇采样转发干扰可以获得雷达脉冲压缩增益,对雷达系统构成了很大的威胁。针对采用线性调频脉冲压缩和单元平均类恒虚警检测的雷达系统,在分析了间歇采样重复转发压制干扰原理和雷达恒虚警检测的工作原理的基础上,理论分析推导了不同间歇采样占空比、转发增益和不同的噪声功率背景条件下重复转发干扰在真实目标CFAR检测区间的能量。通过分析信号能量、噪声能量和干扰能量之间的关系,推导了不同干扰参数下CFAR检测器的信噪比。研究结果表明,在重复全转发这种干扰样式下,采样频率、占空比均是影响影响检测器的重要参数,当优化参数配置,使得转发能量尽量位于检测单元内时,有相对理想的对抗效果。

Planetary Defense From Space: Part 1-Keplerian Theory

A system of two space bases housing missiles is proposed to achieve the Planetary Defense of the Earth against dangerous asteroids and comets. We show that the layout of the Earth–Moon system with the five relevant Lagrangian (or libration) points in space leads naturally to only one, unmistakable location of these two space bases within the sphere of influence of the Earth. These locations are at the two Lagrangian points L1 (in between the Earth and the Moon) and L3 (in the direction opposite to the Moon from the Earth).

We show that placing bases of missiles at L1 and L3 would cause those missiles to deflect the trajectory of asteroids by hitting them orthogonally to their impact trajectory toward the Earth, so as to maximize their deflection. We show that the confocal conics are the best class of trajectories fulfilling this orthogonal deflection requirement.

An additional remark is that the theory developed in this paper is just a beginning of a larger set of future research work. In fact, while in this paper we only develop the Keplerian analytical theory of the Optimal Planetary Defense achievable from the Earth–Moon Lagrangian points L1 and L3, much more sophisticated analytical refinements would be needed to:

1. Take into account many perturbation forces of all kinds acting on both the asteroids and missiles shot from L1 and L3;

2. add more (non-optimal) trajectories of missiles shot from either the Lagrangian points L4 and L5 of the Earth–Moon system or from the surface of the Moon itself;

3. encompass the full range of missiles currently available to the US (and possibly other countries) so as to really see “which asteroids could be diverted by which missiles”, even in the very simplified scheme outlined here.

Outlined for the first time in February 2002, our Confocal Planetary Defense concept is a Keplerian Theory that proved simple enough to catch the attention of scholars, representatives of the US Military and popular writers. These developments could possibly mark the beginning of an “all embracing” mathematical vision of Planetary Defense beyond all learned activities, dramatic movies and unknown military plans covered by secret.

The real aerospace plane

In this article reproduced from Aerospace, Spring 1986, James Haggerty reports on the US National Aerospace Plane (NASP) research programme. NASP is a joint Department of Defense/NASA programme to develop and demonstrate the technologies for a revolutionary class of aerospace vehicles, powered by airbreathing engines, that would have the capability to take off from and land horizontally on standard runways, cruise in the atmosphere at hypersonic speeds, or fly into low-Earth orbit. The Air Force has been named executive agency for the programme. NASA is charged with overall technology direction. Other DoD participants include DARPA, the Navy and the Strategic Defense Initiative Organization.

In April 1986, the USAF awarded development contracts to seven aerospace manufacturing firms. Contracts for air-frame design went to Boeing Aerospace Company, Lockheed Advanced Aeronautics Company, General Dynamics Corporation, McDonnell Douglas Corporation and Rockwell International Corporation. General Electric Company and Pratt & Whitney Division of United Technologies were awarded propulsion contracts.
