Performance Analysis of an Ultra-Low Side Lobe Non-Linear Frequency Modulation Signal for Pulse Compression

In this paper, we present a new frequency modulation function on the basis of features of traditional non-linear frequency modulation signal. This function is in accordance with S-type curves in function values, first derivative and second derivative. This model function unifies linear and non-linear frequency modulations. Next, this paper gives the processing algorithm and simulation results using a typical S-band air traffic control radar as an example. In the end, this paper discusses the application of the model function to the air traffic control radar.
