1. A radar transmission system comprising: a processing system configured to generate pulses; a transmitter system configured to convert the pulses into one or more radar signals; and an antenna system configured to radiate the radar signals, wherein the processing system, the transmitter system, and/or the antenna system are configured such that the radiated radar signals include a pattern of radar pulses having: at least two neighboring radar pulses that have a separation that is substantially unequal to the separation between at least two other neighboring radar pulses in the pattern of pulses; and radiation patterns that result from this substantially unequal separation having: a mainlobe with a width that is near or substantially equal to the minimum possible mainlobe width; and sidelobes with substantially even energy distribution.
