Q.7. Assume a radar receiver with gain of 100, has an IF bandwidth of 4GHz, and a noise figure [10M] of 6.3, transmitting 31.62KW of power at a frequency of 8 GHz, for a target cross section of 8m². (Assume TO = 290 degrees kelvin., and k= 1.38 x10-23) A. Convert radar equation into decibel e radar equation, applying decimal log on both sides and find the new equation for range, [4M] B. Convert all the values into decibel and use it in the above expression to find maximum range. [3M) C. Calculate the Maximum range without decibel rule, (with Absolute equation) and compare the value with Answer of part-B. Justify the reasons for change in value. [3M]
