Abstract

The detection capability for low radial velocity targets is an important measure of radar performance. Facing the challenges that low radial speed targets cannot be detected in the frequency domain and the limitations present in time domain detection, this paper proposes a waveform parameter design method to improve this issue. Under the premise of ensuring a safe distance between the target and the main lobe in the time domain, this method first determines the possible range of values for the pulse repetition frequency. Then, considering the limitations of the radar's own hardware conditions, specifically the restrictions on the transmitted waveform pulse width, the method maximizes the pulse repetition frequency and pulse width based on these conditions, to achieve the best effect in time domain detection of low radial speed targets and maximize radar detection performance. Finally, this paper uses this method to provide a suitable selection scheme for radar waveform parameters at any moment in the dynamic process of missile targeting.
