Pulsed radar system and method of operating a pulsed radar system

A method for operating a pulsed radar system, wherein the pulsed radar system comprises:

• a transmitting antenna, configured to transmit transmission signals,
• a receiving antenna, configured to receive reflected signals,
• a signal generating means, configured to generate transmission signals, and
• wherein the method comprises the steps of:
• generating a first transmission signal at a first centre frequency,
• generating a second transmission signal at a second centre frequency, wherein the first centre frequency differs from the second centre frequency, and
• transmitting the first and the second signal during a predefined transmission time window,
• wherein the transmission time window extends from a start time t0 to an end time tmax, and
• wherein transmission of the first transmission signal is performed between the start time t0 and the end time tmax, and
• wherein transmission of the second transmission signal is performed during a first predefined period of time starting after the start time t0 and ending at the end time tmax,
• whereby the transmission of the first transmission signal and the transmission of the second transmission signal ends at the same time,
• wherein when the first transmission signal hits a target a first reflected signal is generated and when the second transmission signal hits a target a second reflected signal is generated,
• wherein the centre frequency of the first reflected signal correlate to the centre frequency of the first transmission signal and the centre frequency of the second reflected signal correlate to the centre frequency of the second transmission signal, and
• wherein the method further comprises the method steps of:
• receiving the first and/or second reflected signal, and
• separating the first and second reflected signals by means of their respective first and second centre frequency.
