Abstract
The range corrector circuit uses two counters, one for the apparent range (R.sub.a) and one for the correct range (R.sub.c), and a random access memory (RAM). The R.sub.c counter is continuously incremented linearly and the R.sub.a counter is incremented in accordance with a range correction equation. Both counters are reset to one every time a transmitter pulse is received. A linear sweep is also initiated on the plan position indicator (PPI) display of the bistatic passive radar at that time. Target returns are entered into the RAM at the address specified by the R.sub.c counter and are read out of the RAM and applied to the PPI display at the address specified by the R.sub.a counter.
