Method for generating a signal with a definable pulse shape

1. Method for generating a pulse-shaped transmitted output signal having a definable pulse shape, via a multistage amplifier arrangement, in which the course of the pulse top of the transmitted signal is determined by control signals at the respective amplifier stages; said method comprising:

forming the control signals of the respective amplifier stages by sequentially combining pulse sections of a predefinable frame pulse;

wherein, the course of the tops of the pulse sections each have a predefinable constant gradient.

2. The method according to claim 1 , wherein the amplifier stages are emitter-modulated.

3. The method according to claim 1 , wherein the frame pulse is digitally shaped and is subsequently converted in an analog manner.

4. The method according to claim 3 , wherein:

the pulse sections are conjoined to form a frame pulse;

the frame pulse is used to form the control signal; and

the gradient of the course of the tops of the individual pulse sections of the frame pulse is negative or positive.

5. The method according to claim 4 , wherein the pulse sections have variable definable pulse lengths.

6. The method according to claim 5 , wherein the control signal is formed based on a frame pulse that has a definable pulse length of up to 32 μs.

7. The method according to claim 6 , wherein the number of frame pulses corresponds to the number of amplifier stages.

8. A method for generating a pulse, shaped output signal via a multistage amplifier arrangement in which a course of the output signal is determined by at least one control signal that is used to control the amplifier arrangement, said method comprising:

generating a predistorted control signal having a shape that is complementary to distortion of said pulse signal which results when a rectilinear control signal is used;

applying said predistorted control signal to at least one stage of the amplifier to generate said pulse shaped output signal;

wherein said step of generating a predistorted control signal comprises,

forming a frame pulse comprising a sequential conjunction of a plurality of pulse sections, each of said pulse sections having a predefinable variable length and an upper edge that is characterized by a constant gradient said sequentially conjoined pulse sections collectively having an upper edge with a shape that corresponds to said complementary shape of said predistorted control signal; and

using said framing pulse to form said control signal.

9. The method according to claim 8 , wherein the control signal is formed based on a frame pulse that has a definable pulse length of up to 32 μs.

10. The method according to claim 8 , wherein the number of frame pulses corresponds to the number of amplifier stages.
