Hi Mugsby, I'm sorry but I haven't uploaded it!I have downloaded it :) , I got this link from other source...... You can see the pictures if you left click on the boxes which r there for the pictures.......I did this and got the schematics........ free! whenever I tried to see the projects at silicon chip,I was asked to pay for it.....some other members also say that they can get it free but I don't know why I can't....... Repair shop guys storys????????????

Logan you r veru lucky then ;D :-[ u can see,it's still not working for me

just for telling.....this has paused working for me since 8th June......getting a list of messages upto 8th june ony......

http://www.hpa.org.uk/radiation/understand/information_sheets/mobile_telephony/background_info.htm "The mobile phone networks in the UK use frequencies close to 900 MHz, 1800 MHz and 2000 MHz, where the unit MHz (megahertz) is a million cycles per second"

I am not saying that the site has any problem....I was only asking about the message..... Thanx

While downloading files(books) from e-lab with RegetDeluxe.....I'm getting a mesage when my internet connection is disturbed that"Resuming is not supported by the destination server"....Can any one tell me what' this....

schematics in service manuals ::) e-lab has radar detecter in projects section.....

? I will design it :)...but for that we have to wait for atleast 1-2 yrs. :) since this subject is not included in my course this year......I am unable to understand themethod upon which e-lab project is based....Can u tell me which method of the two looks good....And please don't get angry with me....I can't leave that work which seems to be hard or impossible....I always try to make it possible ....It's my habit.

Laser radar block diagram and explaination:- http://profusion.ittc.ku.edu/publications/documents/Allen2002_RSL%20TR%2018680-2.pdf

I think for that u must know the transmitted frequency ......Can it be known here? how's the variation of the frequency taken and passed to display speed(in which part of the crkt, as mixer is used for rf crkts) ?..... U said 74hc can be used here.....I again read the desciption of the crkt and it says ttl type shoulb be used.....74hc is cmos type?? Thanx

-------------------------------------------------------------------------------- How do radar guns work? Radar guns utilize the "Doppler principle" to determine speed. They transmit radio waves at microwave frequencies, and when these waves strike a moving object, they are reflected back to the radar gun at a slightly different frequency. The gun then "mixes" the reflected signal with the transmitted signal, and ends up with a frequency that represents the difference between the two. Since the difference in frequency is generally a number of hertz or kilohertz, it is in the audible range, hence the term "Doppler tone". The speed of the moving object can be derived by performing a calculation using the frequency of this Doppler tone and the original transmit frequency. -------------------------------------------------------------------------------- How do laser guns work? "Laser guns do not use the Doppler principle" like radar guns do. Instead, they use "time difference of arrival". The laser gun sends out a pulse, and calculates the "time of flight" for the pulse to be reflected back to the laser gun. Since the speed of light is a known value, the distance between the laser gun and it's target can be calculated by the time of flight. The laser gun takes multiple distance measurements, and by comparing the different distance measurements over time, it can determine the speed of the target. What are FMCW and AMCW trying to do here http://www.swedetrack.com/obstact.htm#4 ?

"Magic"....yeah I think you're right :-\

Can this one be added with yours,Ante? mobile_jammer.pdf MAX2360-MAX2364.pdf

yeah,Acc to my knowledge,doppler shift occurs to the modulation frequency......But how is it useful......Just leave the crkt at electronics-lab and tell me that how he counting of the received signal with doppler shift can be useful?How can it be converted to speed?Just ideas not referencing the ladar crkt if it is wrong..... yes,that's what I was saying about the ring pin:- The signal entering in the ramsey display schematic(low pass filter) is the doppler shift? which is, for 2.6 GHz case, 7.76Hz for each mi/hr.....So,the crkt may be designed for 7.76Hz(or it's multiples to masure the speed like this 7.76*10=77.6 which means 10 Miles/hr)?????.....

and this one.... Thanx

Yeah, Audioguru,it is hard to understand without the details of the project.....I don't know where to find about it.....Googling didn't help me...... Sorry!any idea about this :-[

What's the purpose of this(see labeled block)? I m unable to find a good detail on ladars in google......Have u any? there are many about radars but none explaining the steps of ladar..... You say that there is no mixer in our ladar......then It is not using the doppler shift????? Since the mixer will give us the doppler shift...... Are ladars absolutely different from radars? Still I don't get how to determine the transmitted frequency in ladars....... This seems to me giving no results :'(

I thought the output of the mixer is going to low pass filter.....Then what else?

The signal entering in the ramsey display schematic(low pass filter) is the doppler shift? which is, for 2.6 GHz case, 7.76Hz for each mi/hr.....So,the crkt may be designed for 7.6Hz..... Can we FM modulate the laser beam?how? at 2.6GHz? If we fm modulate it and after the signal is received ......we pass both the signals(transmitted and reflected) in a mixer and gets their difference, the doppler shift and if we have 2.6GHz transmitted signal ,then we only have to connect the transmitter and receiver+mixer part to the ramsey

:o oh! I thought u were referencing photo diode....the mixer not present in our circuit(laser)???? How can that RF modulated frequency be determined in the ladar? By now what I've learnt is that the rf frequency should be known.....I can't see without that how one can proceed ...... RF modulated...Frequency Modulated ..I think?

I went through a link in google....and it says that for 2.6GHz transmitted frequency the doppler shift for eachmi/hr is 7.74.......... How to calculate the transmitted frequency in this case of ladar? So,I think that was what I was trying to claculate ...... But the formula can't do it.......Can't a laser beam transmitted with a known frequency?? ( - Doppler Lidar - Measures the velocity of a target - Light transmitted from lidar hits target moving towards or away from the lidar, wavelength of light reflected/scattered off the target will be changed slightly- Doppler shift - If target moving away from lidar, return light will have longer wavelength (red shift), or shorter wavelength if moving towards lidar (blue shift) ) (Radiation used by laser radars is at wavelengths 10,000 to 100,000 times shorter than that used by conventional radar )
