Radar signal transmit power shaping and processing

A radar device comprising:

• a radar front end comprising:
• transmit signal generation circuitry configured to generate a radar transmit signal sequence comprising a plurality of radar transmit signals;
• a power shaping component configured to receive the plurality of radar transmit signals of the radar transmit signal sequence and output the plurality of radar transmit signals with a plurality of different power levels;
• and
• a transmitter to transmit the plurality of radar transmit signals based on the plurality of different power levels, wherein the plurality of different power levels is based on a power profile associated with a window applied to digitized samples of reflections of the transmitted plurality of radar transmit signals;
• and
• a radar processor to apply the window across a slow-time of the digitized samples of the reflections prior to velocity fast Fourier transform (FFT) processing of the digitized samples of the reflections;
• wherein the power profile corresponds to a square root of weighted coefficient values of the window if the window was only applied at the radar processor.

A method comprising:

• generating a plurality of radar transmit signals at a constant power level;
• modifying the constant power level of the plurality of radar transmit signals to a plurality of power levels according to a power profile to produce a plurality of modified radar signals, the power profile including a subset of weighted coefficient values of a second window applied by signal processing components of a receive chain that applies a first window and the second window;
• normalizing the plurality of modified radar signals to have one of a first power output or a second power output, wherein the first power output has an average power level that matches an average power output of the plurality of transmit signals at the constant power level, wherein the second power output produces a signal-to-noise ratio (SNR) that matches an SNR of the plurality of transmit signals at the constant power level;
• and
• transmitting the plurality of modified radar transmit signals based on the plurality of power levels.
