1. Attempt any two questions [2×15=30]
   1. Derive the expression for simple form of radar range equation. Radar is operating at 1.5cm with peak pulse power of 300 kW. The capture area of antenna is 5m² and minimum detectable signal is 10^-12 W. Calculate the maximum range of radar if radar cross section of target is 10 m².
   2. Explain various system losses in detail.
   3. Write short note on:
      1. Low angle tracking
      2. Delay line canceller
