Broad band radar for e.g. detection of aircraft, has battery of filters that are adapted to signals which are received from types of targets, where filters have frequency band which is emitted band

摘要

The radar has a battery of filters (1 1- 1 n) that are adapted to signals which are received from types of targets, where the filters have a frequency band which is an emitted band. The battery of filters comprises a set of N 1filters that is in parallel and with adjacent bands and a combination unit for making linear combinations of the signals obtained from the filters, corresponding to searched transfer functions. Analog-digital encoders are placed after each filter, where each encoder has a sampling rate which is inverse of the band.
