This document describes a web-based client-server model for controlling electronic warfare monitoring receivers remotely. The system allows a client to intercept and demodulate signals like AM and FM using a receiver that can be configured and controlled via TCP/IP through a LAN connection to a server. Key components include the client, server, router, and specifications for IP addresses, longitude/latitude, and system requirements.

1. A Web Based Client and Server Model for Controlling Electronic Warfare
Monitoring Receivers
Abstract:
The basic concept of electronic warfare monitoring receivers is to exploit the
enemy’s signals. It is to provide intelligence on enemy’s order of battle, intentions
and capabilities where to use some countermeasures to deny effective use of
communications. The signals can be detected by using frequency, bandwidth and
demodulation. Here, we are going to control the electronic warfare receiver by
using web based client and server.
The monitoring receiver can detect the different modulation signals such as
Amplitude modulation, frequency modulation, and pulse signal etc. our project
includes controlling of monitoring receivers to intercept and demodulate mainly
AM,FM modulated communicated intelligence by controlling and configuring the
receiver with the relevant command structure. The receiver is remotely controlled
via LAN using TCP/IP protocol.
Modules:
Client
Router
Server
Ip address
Longitude and Latitude
Client:
The client is the end user of the network and needs to be secured the most. The client end usually
exposes data through the screen of the computer. Client connections to server should be secured
through passwords and upon leaving their workstations clients should make sure that their
connection to the server is securely cut off in order to make sure that no hackers or intruders are
able to reach the server data. Not only securing the workstations connection to the server is
important but also securing the files on the workstation (client) is important as it ensures that no
hackers are able to reach the system. Another possibility is that of introducing a virus or running

the server.
Server:
The server can be secured by placing all the data in a secure, centralized location that is protected
through permitting access to authorized personnel only. Virus protection should also be available
on server computers as vast amounts of data can be infected. Regular upgrades should be
provided to the servers as the software and the applications need to be updated. Even the entire
body of data on a server could be encrypted in order to make sure that reaching the data would
require excessive time and effort
Router:
A router is a device that forwards data packets between computer networks, creating an overlay
internetwork. A router is connected to two or more data lines from different networks. When a
data packet comes in one of the lines, the router reads the address information in the packet to
determine its ultimate destination. Then, using information in its routing table or routing policy,
it directs the packet to the next network on its journey. Routers perform the "traffic directing"
functions on the Internet. A data packet is typically forwarded from one router to another through
the networks that constitute the internetwork until it reaches its destination node.
IP Address:
An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g.,
computer, printer) participating in a computer network that uses the Internet Protocol for
communication. An IP address serves two principal functions: host or network interface
identification and location addressing. Its role has been characterized as follows: "A name
indicates what we seek. An address indicates where it is. A route indicates how to get there
Longitude and Latitude:
Longitude:
It is a geographic coordinate that specifies the east-west position of a point on the Earth's surface.
It is an angular measurement, usually expressed in degrees and denoted by the Greek letter
lambda (λ). Points with the same longitude lie in lines running from the North Pole to the South
Pole. By convention, one of these, the Prime Meridian, which passes through the Royal
Observatory, Greenwich, England, was intended to establish the position of zero degrees
longitude.

3. Latitude:
It is a geographic coordinate that specifies the north-south position of a point on the Earth's
surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North
or South) at the poles. Lines of constant latitude, or parallels, run east–west as circles parallel to
the equator. Latitude is used together with longitude to specify the precise location of features on
the surface of the Earth.
