i can only pitty your IGNORANCE!! DRDO has manufactured this master piece all by itself.. the basic fundamental block of our AESA i.e t/r modules were indigenously manufactured by ASTRA MICROWAVES.. our 8-CHANNEL TRMM is a master piece of engineering and yes DRDO has a PATENT for that.. i am...

sir,the WDG-5 is the most powerfull diesel loco..as it churns out 5500hp... but you can get even more powerful latest electric locos with 6500hp capacity like the WAG-7,9 etc...

sir with due respect,i am NOT here for trolling but for serious discussions,so time for some reality check up- 1)chinese indigenous locomtives are **** and cant run in indian sub continent conditions,whereas indian WDM-3,4,5 class engines are working fine in indian conditions for so long...

@OSCAR... here is the complete pdf about the patent granted to LRDE(related with their advanced/revolutionary) t/r modules,go through it completely... this is why,you go for patent as soon as you produce something "original" after years of painstaking research(NOT by epsionage)...hope you get...

@oscar... T/R Module Technology DRDO

WRONG!! patents are very well applicable in case of t/r modules!!haan,provided you have painstakingly developed it on your own(NOT copying work like chinese),we had a huge seminar on this,when i attended dr christopher's seminar about the indian t/r modules(LRDE currently holds the patent of...

you must be kidding right?lol...hey,would love to continue discussions on these topics...:-) hey,bro,but i find it extremely hard to buy your logic when you say,the T/R modules have been designed there...i mean,"designing" requires a lot of research,and once you have diligently designed a new...

ohh but MSP-430 is very revolutionary...:-) much better performer than itz compitetors... over here,we use BGA as well as DIP ...what about in pak?

well thats "explains" why pakistan lacks "PATENT"!! and over there countering india means gathering stuff either by hook or crook...:-) yet pakistan lacks indigenous r&d to produce stuff on lines of rajendra PESA,WLR,FLR,ADITYA-AESA,LRTR(sword fish) BTW,by any chance have you ever done any...

i am axiously waiting to see some really serious stuff across the border... but given the "state of affairs" of r&d and "ground realities" i am more inclined to think otherwise

something is NOT right here!! research over there in pakistan is very different from research over here...

@farhan...bhai,nice to see you around...:-) salaam! :smitten: do you think,US is that fool to let anyone else "reverse-engineer" their t/r modules? and secondly,mind it,no one,actually "transfers" the tech of t/r modules!! NOT even china will "transfer" their secret of t/r modules to pakistan...

since when does pak started manufacturing T/R modules of a highly sophisticated american radar? sir ,with due respect,do you even know what it takes to design t/r modules? sir pak or for that matter any country declare what it achieves,be it nasr,IRBMs,etc etc, so ,they would be the first one...

so you mean to say that,pakistan has designed the modules(with no prior experience) and sent the modules to china for fabrication? then why doesnt they reveal the names of the systems that has been designed there sir i too work at india's premier manufacturing facility yet i find extremely hard...

sir,given the history of amount of research work done in pakistan,i really dont think thats possible, sir,do you know how much research is involved in developing a t/r module? let alone t/r module,have you gone through the PSM unit of a PESA? IF what you are stating is correct,then why...

sir as far as my knowledge of research and development goes, 1)the research lab produces a "prototype" model of the antennae element,which includes designing the t/r modules in case of AESA and PSM in case of PESA... 2)the prototype is then sent to manufacturing units/manufacturing factories...

sir,with due respect,i am NOT aware of any indigenous phased array systems in pak, havent heard of them, and secondly,which institute in pak,does the research work on PSM modules,or t/r modules?do they have patent? i know about the erieye and zdk-03,but they are swedish and chinese respectively

wow,great, so,you work in pakistan?or somewhere else?if i am NOT mistaken,then pakistan has NO phased array radar,manufactured in pakistan? sir,with due respect,i dont think,pak has any indigenous phased array radar systems?though i would be glad if you can shed some more light

i hope so...lol...i didnt say anything about the frequencies...:cheers: only the bands...;)

many people over here doesnt know that,rajendra radar system consists of three separate radars(all of them phased array)- 1)c-band surveillance radar 2)x-band fire control radar 3)IFF radar
