Abstract: A method for filtering and removing false targets caused by sidelobes in pulse compression calculates the target filtering threshold to differentiate and eliminate false targets caused by sidelobes in pulse compression. It is applicable in radar signal processing systems using the polyphase P3-coded waveform (the P3 code) for both transmitted and received signals. This method leverages the characteristics of the P3 code's pulse compression output. Specifically, the sidelobes appear symmetrically on both sides of the main lobe, and the distance between the main lobe and the sidelobes is approximately equivalent to the pulse width of the transmitted signal, extending to both sides of the main lobe. For each pulse width of the signal, this distance is fixed and can be predetermined. Experimental results on radar systems have demonstrated that the proposed method effectively filters out all false targets caused by sidelobes in pulse compression.

Abstract: Far-field antenna pattern measuring system and solution using real-time synchronization of height information helps better the detecting and tracking quality of the 3D radar, paving the way to determine the pattern's practical shape and the impacts of the ground on it to find the accurate height tracking methods. The proposed system is comprised of 5 steps: step 1: get and save height information; step 2: get and save power information; step 3: plot the obtained pattern shape; step 4: determine the obtained pattern parameters; step 5: save lobes parameters into a table and assess in the association with the simulation results.
