A portable Doppler microwave radar defense system that saves lives in dangerous situations, and alerts a person from surrounded threats, exposes enemy location, and shows the health data and injured person's location to remote server at a base. The system lets the person know about the surrounded threats before it happens, as it will detect any bullets in the detection zone and alert the person immediately from the incoming bullet within a long range which will let the person have seconds to avoid the bullet and save his life and the location of the shooter will be exposed to the person. The detection system can also be deployed over an object such as a car, truck, battle tank, aircraft, jet, helicopter, spaceship, or a satellite.

An explosive device detection and expulsion system broadly comprising a detection subsystem for sensing an IED attached to a vehicle and an expulsion subsystem for expelling the IED from the vehicle. The detection subsystem includes a sensor for detecting an IED via an electromagnetic field change or capacitance change, vibrations, and/or heat, and a controller for activating the expulsion subsystem upon receiving a detection signal from the sensor. The expulsion subsystem includes a deployable panel configured to be attached to the vehicle and a deployable mechanism for shifting the deployable panel from an undeployed state to a deployed state so as to expel the IED from the vehicle.

A high-speed projectile barrier is disclosed. The barrier includes a core structure and a layer or layers of insulation around the core, surrounded by outer skins. The core is made from liquid material that flows at room temperature and that solidifies at cryogenic temperatures, and filler material. The filler may be, e.g., cellulose, carbon nanotubes, carbon nanofibers, or other high-strength polymeric fibers. Other contemplated filler materials include natural or artificial, layered silicate minerals. A viscosity-enhancing additive may be included. A heat transfer element runs through or around the core and is used to freeze (i.e., solidify) the core. The layers of insulation may be vacuum layers and/or layers of foam rubber, aerogel, glass fiber insulation, or other suitable materials.

A reactive armour module and method for providing protection against a tandem warhead, the tandem warhead providing a primary explosion followed after a small preset delay by a main explosion, the method comprising detecting the primary explosion, and detonating a directed blast, towards the end of the small preset delay, that disrupts the secondary explosion.
