Range corrector circuit for a bistatic passive radar display |
July 28, 1981 |
| 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 correc |
