SOLDIER

When

tomorrow's

soldier

wants

to spot

a target

in

an

area,

he will

simply

switch

a

control

on

the back

of

his weapon.

The

world's

smallest

radar will

then

look

over

the

situation,

let

its

soldier

boss

know

when

it

spots

a target

by

emitting

a

series

of

eerie

sounds.

Ranging

all

the way

from

a low

groan

to

a

high

-pitching

squeal,

such

noises

will

reveal

whether

the

radar has spotted

a

walking

man,

a crawling

man,

a man who

is running,

or

a speeding

vehicle.

Doppler

Squeals.

In

essence,

the

radar

-like

any

other -is

simply

applying

Dop-

pler know -how,

the

principle

that

says

a

sound

or

radio

wave

shortens

as the

emit-

ting object

moves

toward

the listener,

length-

ens as

the object

moves

away.

And

the

Doppler

effect

in

this

2 -lb.

radar wonder

results

from

the

frequency-

or pitch

-change

in

the radar's

9 -gHz

signals,

which,

con-

verted

to

sound frequencies

in a

headset,

can tell

the

soldier which

type of

target

he

has spotted

and where

it is.

In

battlefield

operation,

the

Doppler

re-

turn will

sound

much

like

an off

-key

siren

winding

up

when

the vehicle

it

spots is

moving

away.

Since

the

up and

down

and

lateral

vibrations

of

a truck

all

show

dif-

ferent

rates

from

those of

a small

vehicle

such

as a jeep,

the

characteristic

differences

between

targets

are distinctly

discernible

-

even when

pickup

targets

are traveling

The

spots almost

anything

that

moves

and

at almost

any speed -from

2 feet

to over 45

miles

per hour.

And

while

performing

its duties

it puts

up with

no nonsense

from

the

enemy.

In fact,

it is

virtually

immune

to jamming,

and

a

the radar

into

for
