Radar is hampered in its ability to discriminate between targets whose ranges are very close because of the inability to send much energy in a very short-lived pulse. This article describes a multi-pulsed method which enables longer (but many more) pulses to be sent and much clearer pictures of range-velocity cluster environments to be obtained. We consider a radar system detecting a finite number of targets moving in space where objects have ranges x1,...,xm and radial velocities y1,...,ym, respectively. A density function D(x,y) can be defined, where x and y are range and velocity coordinates. This function D(x,y) is zero except at the points (xj,yj), j=1,...,m.
