“…A nanosecond pulse generator based on Avalanche transistor 900 ps pulse width and an amplitude of 25.2V [19] Compact step recovery diode sub nanosecond pulse generator amplitude of this pulse reaches 7.5 V, and the pulse has an Full-Width at Half-Maximum of about 110 ps where 𝑷 𝒓 is the total received power, 𝑷 𝒕 is the total transmitted power,𝑹 is the range of the RADAR and the most crucial term here in this equation is 𝑳 which is termed as the loss component. So, the range of the RADAR depends on the loss component, which itself depends on the wavelength (λ) of operation, target size, the conductivity of the target (σ), property of the ground, etc.…”
