A Formalization of Missile Soft Kill Part I 05

This video presents a formalization of missile soft kill, applicable to drone countermeasures also.
Soft kill refers to the defeat of a guided missile or drone without physically destroying the weapon - so it's more or less synonymous with jamming. Soft kill is the outcome that the jamming is intended to achieve.
In all the decades I have been in the missile and EW/ECM business I have heard endless talk about "soft kill", but never a definition of what it is.
So I created one in 1996: Soft kill means the missile has developed an unrecoverable heading error.
It is by far the most professionally and personally destructive idea I have ever had, most days I wish I had never thought it up. Her...

Multipath Canceller Spatial and Freq 15

Просмотров 652 месяца назад

This video shows some results for an initial design of a Multipath Canceller: a device intended to remove multipath from the signal measured onboard a ship from a terminal-phase radar homing antiship missile. The system cancels multipath by continuously searching for and measuring the peak Rx power, so it effectively "surfs" the multipath peak gain as the missile approaches the ship. It does th...

This video is the third of three videos about a methodology to choose selected parameters for a jammer to counter naval anti-ship drones, guided by an operator using a video link. The video illustrates how to use the methodology to choose only two parameters, to illustrate the process: jammer Tx antenna height, and jammer Effective Radiated Power (ERP). For different or more parameters, the pro...

Effect of Jamming Against Surface Drone Attack 23

Просмотров 2155 месяцев назад

Introductory look at the effect of using an active onboard jammer for ship defence against attack by video-controlled surface drones, relevant to for example protecting military and commercial ships against attack in the Red Sea. The drone notionally becomes unguided once the jammer breaks the drone operator's video link; surface waves subsequently cause low-bandwidth heading noise. Probability...

There are currently no practical options for non-military long-term defence of commercial ships against attack by radar homing missiles, as is occurring in the Red Sea and present. Lethal self-defence weapons cannot be legally fitted to commercial ships inside 12 nautical miles from any shore. A jammer is a nonlethal option, and although there are a number of systems to choose from, each must b...
