The article describes algorithms for the retrieval of linear frequency modulated (LFM) pulses from a received signal which is corrupted by noise and multipath reflections from ground and stationary objects. Such a problem appears, for example, in ele

Tapering an active array antenna system on transmit lowers the sidelobe level, but it adversely affects equivalent isotropically radiated power (EIRP) by reducing both power and gain. In this article, we analyze this effect. First, we propose a new t

One of the reasons which impede applications of ultrasonic beam deflection flowmeters is their calibration that usually needs to be performed across the whole range of measured flow rates. In this paper we have aimed to show that given the directivit

The advantages of passive radars include quiet operation and the ability to detect targets that were designed to be “stealth” for active monostatic radars utilizing higher frequency bands. As the technology of ground-based passive radars is alrea

Multi-channel RF signal acquisition is a typical requirement in modern communications and radar applications. The use of multiple general-purpose Software-Defined-Radio receivers, connected to a host via USB interface, seems to be an attractive solut

The output of the quadrature demodulator is generally regarded as a complex signal that is circular if only the demodulator is well balanced. In the paper we analyze properties of quadrature demodulators, particularly digital one, and show that the o

In the paper, we are concerned with FMCWradar detection of an accelerating target, echo of which is buried in an additive white Gaussian noise. We derive and analyze three-dimensional generalized ambiguity function for target range, velocity and acce

In the paper there are shown four realization structures of matched filtering and beamforming in a coherent MIMO radar with collocated antennas. Particularly, in one of the structures only one matched filtering (per beam and per Doppler frequency) an
