1.	A typical radar is located at 4 meter distance from an object. If radar transmits signal from that position then, signal strength S will be __________(a) proportional to (1/4^4)(b) proportional to (1/4^6)(c) proportional to 4(d) proportional to 1/4I have been asked this question during an interview.I need to ask this question from Configuration Layout Considerations in portion Configuration Layout Considerations of Aircraft Design
Answer» The correct choice is (a) proportional to (1/4^4) For EXPLANATION: Given, Distance d =4m. Since, no other parameters have mentioned we will directly use the relation between STRENGTH and the distance to FIND required relation. Typically, RADAR strength is proportional to (1/distance^4) = (1/4^4).
