Question

What is sound shadow?

Answer 1

Waves tend to bend around large obstacles (e.g. buildings) and the sound intensity is often low immediately behind the obstacle; and Sound gradually regains its original level as he moves out of the shadow. The arrival of two sounds from different directions will give confusing indications of direction; and If only reflected waves are received then the source will appear to be much further away and in the wrong direction

Answer 2

a. Must be sited to facilitate communication with the CP; b. Must be sited to achieve coverage of NAI’s / TAI’s; c. SODOF must be APLLIED d. Must be away from any Main Supply Route (MSR); and e. It should be able too deploy in a standard deployment.

Answer 3

* Topography, (Ground features and man-made Objects); * Sound Shadow; and * Meteorological Conditon, (Wind speed and direction, Temperature, humidity). * Frequency of the sound

Answer 4

4 for accurate

Answer 5

Lack of Knowledge Carelessness Stupidity

Answer 6

1 8 + SPs Operational 2 4 - 7 SPs Operational 3 2 - 3 SPs Operational 4 Non Operational 5 System inoperable for tasking from……. To…….

Answer 7

Not possible to restore the equipment to usable condition either by repair or by cannibalisation. * Classified equipment must be destroyed in such degree as to prevent, whenever possible, duplication by, or determination of operation or function by, the enemy.

Answer 8

* Burning: Explosive fire hazard. Gasoline and gasoline vapour are an explosive fire hazard. There must be no smoking or naked flames in the vicinity while preparations for destruction are being carried out. Cutting cables Smashing Screens * Explosives: Only personnel who are trained in the handling and use of explosives must undertake the destruction of equipment using explosives * Gunfire: The firing of artillery at ranges of 500 yards (450 m) or less and the firing of grenades or anti- tank rockets should be from cover.

Answer 9

AWLS Radio (Raven): * The radio case has an extremely robust construction * Connectors * Cables * Casing

Answer 10

* Connector Panels * CP CMP and CPC * SP CLP * Cables * Meteorological (Met) Sensor Assembly

Answer 11

BATTERY CAPACITY Normal Deployment * The batteries and battery charger for the Canadian DND HALO system are supplied as Government Supplied Material (GSM). Consult the relevant instructions for information relating to battery capacity. * It is essential that the batteries are monitored, and ideally ‘hot changed’ before being completely exhausted.

Answer 12

The strength or power of a wave signal. The "height" of a wave when viewed as a graph. Higher amplitudes are interpreted as a higher volume, hence the name "amplifier" for a device which increases amplitude

Answer 13

The number of times the wavelength occurs in one second. Measured in kilohertz (Khz). The faster the sound source vibrates, the higher the frequency. Higher frequencies are interpreted as a higher pitch. The number of cycles of the wave in 1 sec; Frequency is measured in Hertz (Hz); and The symbol for Frequency is the letter ‘f’ (English, lower-case).

Answer 14

❖ Locating guns and mortars whose trajectory passes below the WLR beam. ❖ Filling gaps in the WLR coverage. ❖ Locating guns and mortars when ECM prohibits the use of WLR

Answer 15

➢ The AWLS is optimised for defensive, linear operations, although it has considerable utility beyond this. ➢ A standard deployment would consist of a line of SPs 3-5 km behind, and parallel to, the FLOT. ➢ For more complex defensive scenarios, this deployment can be modified, with groups of SPs being deployed to cover distinct areas of int

Answer 16

➢ The AWLS sensor has a limited ability to manoeuvre owing to the time taken to deploy the system. ➢ The rates of advance that can be achieved will vary according to conditions. The AWLS can support an advance in contact, with slower rates of advance. ➢ A rapid advance to contact is likely to outpace the AWLS’s ability to provide coverage while manoeuvring. In this circumstance the AWLS can be deployed once contact has been made.

Answer 17

Transportable, relatively passive automatic Acoustic Weapon Locator ➢ Standard system comprises 1 Command Post (CP) and up to 12 Sensor Posts (SPs) ➢ Standard Deployment will see 8 SPs deployed over a frontage of 20 kms ➢ SPs can be remotely located and linked by radio or landline to a CP. ➢ Met abilities at both the CP and SP for increased accuracy

Answer 18

Coverage ➢ The deployment of eight SPs normally provides a frontage of 20 kilometres in which four or more SPs are likely to detect the event.

Answer 19

❖ Digital mapping. ❖ Functioning of the met equipment. ❖ The type and calibre of the gun. ❖ Terrain

Answer 20

Turbulence, direction, Velocity
