AI Thread Summary
The discussion focuses on finding the monostatic Radar Cross Section (RCS) of a flat strip of length a, with the user seeking assistance in applying necessary approximations to achieve a sinc result from their scattered field expressions. They mention having developed the required expressions but struggle with the approximations needed for the calculations. References to the RCS of dipoles and related concepts are provided, emphasizing the proportionality of the dipole response to Sin(θ) for both reception and retransmission. The conversation also touches on historical radar countermeasures like Chaff and Window. Overall, the user is looking for collaborative help to refine their approach to calculating the RCS.

I'd appreciate some help finding the monostatic RCS of a flat strip of length a. I have figured out the necessary expression for the scattered field but am having difficulties figuring out the requisite approximations for arriving at the desired sinc result. If I provided all the expressions, would anyone here be willing to assist?

The wikipedia article explains Radiation Cross Section pretty well...

Unless of course you are asking about something else... :wink:
 
I think you are asking about the RCS of a dipole of length a.
The dipole response for reception will be proportional to Sin(θ).
The dipole response for retransmission will be proportional to Sin(θ).
The radar reflection equation will be the product, so proportional to Sin2(θ)
But the RCS is specified relative to an equivalent sphere, which I believe brings it back to the sinc function.

Google; ' antenna mode RCS of a dipole '
You will find references like; http://www.dtic.mil/dtic/tr/fulltext/u2/a080989.pdf
RADAR countermeasures that employed dipoles as scatterers, developed during WWII, were called Chaff, Window or Duppel.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
