This paper presents new digital multibeam former. Digital multibeam former is capable to synthesize few hundred of beams simultaneously. This concept permits antenna array receiver to receive signals in wide solid angle with the antenna gain corresponding antenna aperture. Target application of the multibeam antenna is the multistatic radar receiver. Methods for parallel and serial beam forming are...
In this work, the hardware implementation of a digital mismatched pulse compressor and its application to a pulse-Doppler radar system are presented. The emphasis is to use one generalized compressor with reloading coefficient capability for several different types of signals. This implementation starts with a generic VHDL specification and then it is developed on FPGA architecture. The compression...
In this paper, a system analysis of needs and possible application of DIRLS mismatched filter in portable surveillance radar PR-15 is presented. Transmitting pulses are binary phase intra-pulse modulated. Because of limited peak power, the usage of longer radar pulses is necessary in long distance mode of operation. Applied binary M sequences have insufficient good autocorrelation properties so a...
