Radar device and method for coding a radar device

A radar system having

• means (12) for generating a code,
• means (18) for modulating a transmitting signal in a transmit branch, using the code,
• means (32) for delaying the code,
• means (20) for modulating a signal in a receive branch, using the delayed code, and
• means (26, 42, 44, 46) for mixing a reference signal with a receiving signal,
• wherein
• the modulation of at least one of the signals is carried out by a phase modulation (PSK;
• “phase shift keying”) and
• means (22, 24, 34, 36) are provided for blanking phase transitions.

A method for coding a radar system, having the steps

• generating a code
• modulating a transmitting signal in a transmit branch, using the code,
• delaying the code,
• modulating a signal in a receive branch, using the delayed code, and
• mixing a reference signal with a receiving signal,
• wherein
• the modulation of one of the signals is performed by an amplitude modulation (ASK;
• “Amplitude Shift Keying”), and
• the modulation of the other signal is carried out by a phase modulation (PSK;
• “phase shift keying”).
