An improved radar detection range plotting method based on radar equation

In this paper, an improved radar detection range plotting method based on radar equation is proposed. Radar equation can be used to plot the radar detection range in theory from the point of view of energy. But in practice, the condition can not be satisfied. Based on radar equation, this method takes ground reflection, atmospheric refraction, earth curvature and obstacle into account, which may affect radar detection range. (i) According to Image Method, analyze the effect of ground reflection to metric waves and centimeter wave;(ii) Amend the height result as the earth curvature;(iii) Remove the Blind Zone as the obstacle by cutting method. The simulation results show that the method can exactly calculate and plot radar detection range.
