ABSTRACT This paper proposes the agile

advancement and improvement in nations

weather, aircraft and military surveillance

system using the innovative multi-function next


2/6

generation electronically phased array radar

technology. It permits multiple functions to be

carried out to NPRN (national primary radar

network) air-traffic cooperative positioning,

FAA enterprise architecture, BMDS (ballisticmissile defence system), air route and airport

surveillance radar, JPDO alignment and

military, and also represents a quantum leap in

naval radar. In the present context, the

simultaneous transmit and simultaneous receive

(STSR) mode independents the time gage of

transmission. The AESA (active electronically

scanned array) radar technology used to prove

this concept. To help the phase of MTI (moving

target indicator), active electronically scanned

array composed of thousands of micro-radar

components, which micro-radar are able to

independently target in different direction by

same radar.

I. INTRODUCTION

The multi-function next generation electronically

phased array radar describes the brief concept for

possible future utilization of The Active

Electronically Scanned Array (AESA) radar to

perform multifunction in a field of next generationradar system. It is a improved version of general

legacy terminal radars (ASR-8 and ASR-9) with

next generation radar system including the combine

concept of multi-function phased array radar

(MPAR) and active electronically scanned array

radar (AESA).

The below figure shows the electronically phased

array radar with many number of micro-radar.

This radar system composed of thousands of

micro-radar components, which micro-radar has

their transmitter and receiver modules which works

based on simultaneous transmit and simultaneous

receive (STSR) mode by broadcasting radio

frequency at certain angle. This module of

transmitter and receiver makes micro-radars to

independently target in a different direction at atime in same radar. An advanced STSR mode

operates at electromagnetic spectrum in the X-band

(8-12.5Ghz) and lower Ku band (12.5-18Ghz) of

frequency ranging.

Operation of radar system as transmitting,

receiving, waveform generation, signal operation

and mechanical moving part are performed under

the current worlds most advanced computer


3/6

controlled system. The radar system also avails a

replaceable assemblies design for faster, easier

repairs or upgrades to hardware and software

modules. For these reasons, AESA life-cycle costs

are expected to be significantly lower than those ofMSAs. The active arrays on the F-22 and F-35

should have almost twice the expected life of the

airframe.

II. AESA TECHNOLOGY

In the next generation radar system, using a AESA

technology the Lincoln laboratory developed a

design for the next generation electronically phased

array radar system as shown in below figure of

radar system.

Radar systems

generally work by connecting an antenna to a

powerful radio transmitter to broadcast a short pulse

of signal. The transmitter is then disconnected and

the antenna is connected to a sensitive receiver

which amplifies any echoes from target objects. By

measuring the time it takes for the signal to come

back, the radar receiver can determine the distance

to the object. The receiver then sends the resulting

output to a display of some sort. The transmitter

elements were typically klystron tubes or

magnetrons, which are suitable for amplifying or

generating a narrow range of frequencies to high

power levels. In order to scan a portion of the sky,

the radar antenna has to be physically moved to

point in different directions.

Functions of AESA:

The below figure shows the configuration of

general next generation radar sets and its operates

up to the mark of multi-function in different fields

of radar.

FAA architecture and JPDO alignment:

The federal aviation administration (FAA) is anagency of the United States department of air

transportation with an authority to license and

certification aspects of civil aviation. FAA roles for

responsibilities in a use of supporting technologies.

Development in next generation radar, it integrates


4/6

vision for operation for on the air traffic and

weather surveillance and cooperative surveillance.

Joint planning and development office (JPDO)

alignment provides data for JPDO modelling efforts

to look at various technologies that can solves theissue occurred to implement the radar system.

By focused on next generation radar system,

aligning the mission benefits and capabilities to

operate at multi-function level the next generation

radar has been licensed and certified by JPDO and

FAA.

In present context the multi-function next

generation electronically phased array radar permits

multi-function to be carried out as national primary

radar network (NPRN), ballistic missile defence

system (BMDS), air route and airport service radar,

military surveillance radar system and also

represents a quantum leap in naval radar.

III. FEATURES

In present context the multi-function next

generation electronically phased array radar permits

multi-function to be carried out as national primary

radar network (NPRN), ballistic missile defence

system (BMDS), air route and airport service radar,military surveillance radar system and also

represents a quantum leap in naval radar.

In general, all the multi-functions are carried out by

the next generation radar. Let consider all above

radar features in different stages as shown below:

NPRN:

As shown above figure the radar system uses for

national primary radar network system. The NPRN

radar system required for foreseeable future. In

further NPRN also uses for general purpose radar

system.

BMDS:

BMDS system developed with innovative advances

in anti-jamming as well as attack protectionhardware technology.

Airport service radar:

AESA replaces current analog systems with new

digital technology to detects aircraft position andweather conditions. Functions include aircraft

separation, weather advisories, and lower level

control of air traffic. The system is designed to

accommodate air traffic growth and the

introduction of new functions which will improve

the safety and efficiency

Military surveillance radar:

This radar provides an unprecedented capability in

air-to-air combat, allowing to track & shoot at

multiple threat aircraft. Solid-state technology and

elimination of mechanical moving parts enables the

Military Surveillance to leap ahead of current

standards for system reliability and field

sustainability.

Naval radar:

An AESA-equipped ship can use the radars agility

and acuity to rapidly develop targets for non-AESA. This also provides improved syntheticaperture radar and automatic target detection/cueing

and better access to geo-location tools, equipped

aircraft or other targets.

Advantages:

< The array of many number of micro-radar

operates multi-tasking at a time.

< The STSR more independents the time gage of

transmission.

< Dramatically increased range and resolution

< Greater lethality and survivability

< Reduced aircrew workload

< Lower maintenance and upgrade cost.
