US 5907301 · granted 1999-05-25
Abstract
A procedure and a device for controlling, in a radar unit for the measurement of target data, the transmission of radar pulses and the reception of target echoes originating from the transmitted radar pulses, in such a way that the performance of the radar unit increases, in order thereby to gain a longer range during a period of time. The period of time is preferably repeated continually. The period of time is divided into a first and a second partial period of time where the first and the second partial periods of time are each at least twice as long as a pulse repetition interval which is used during the first partial period of time. During the first partial period of time the radar unit is controlled so that it transmits radar pulses for the measurement of target data with a higher energy content than what is possible in a steady state. The control is carried out in such a way that the amount of transmitted energy of the radar unit during the period of time is at the most the possible energy transmission of the radar unit in a steady state during a corresponding period of time. There is thereby obtained a more efficient signal integration by means of the signal integration of the target echoes that originate from the radar unit being concentrated during the first partial period of time. The radar unit is also controlled so that it does not transmit radar pulses for the measurement of target data during the second partial period of time.

A procedure and a device for controlling, in a radar unit for the measurement of target data, the transmission of radar pulses and the reception of target echoes originating from the transmitted radar pulses, in such a way that the performance of the radar unit increases, in order thereby to gain a longer range during a period of time. The period of time is preferably repeated continually. The period of time is divided into a first and a second partial period of time where the first and the second partial periods of time are each at least twice as long as a pulse repetition interval which is used during the first partial period of time. During the first partial period of time the radar unit is controlled so that it transmits radar pulses for the measurement of target data with a higher energy content than what is possible in a steady state. The control is carried out in such a way that the amount of transmitted energy of the radar unit during the period of time is at the most the possible energy transmission of the radar unit in a steady state during a corresponding period of time. There is thereby obtained a more efficient signal integration by means of the signal integration of the target echoes that originate from the radar unit being concentrated during the first partial period of time. The radar unit is also controlled so that it does not transmit radar pulses for the measurement of target data during the second partial period of time.
Claim 1
Procedure for controlling, in a radar unit comprising range bins in which target echo energy is signal integrated, the transmission of radar pulses and the reception oftarget echoes during a period of time in such a way that the performance of the radar unit is increased, comprising the steps of: dividing the period of time into a first and a second partial period of time where the first and the second partial periods of time are each at least twice as long as a pulse repetition interval which is used during the first partial period oftime; controlling the radar unit during the first partial period of time so that radar pulses for the measurement of target data are transmitted with a higher energy content than what is possible in a steady state, in such a way that the transmittedenergy of the radar unit during the period of time amounts at the most to the possible energy transmission of the radar unit in a steady state during a corresponding period of time, in order thereby to achieve a more efficient signal integration by meansof the integration of target echoes that originate from the radar pulses transmitted from the radar unit being concentrated during the first partial period
