We report the discovery of an L dwarf companion to the A3V star \beta{} Circini. VVV J151721.49-585131.5, or \beta{} Cir B, was identified in a proper motion and parallax catalogue of the Vista Variables in the V\'{i}a L\'{a}ctea survey as having nea

We present the discovery of 816 high amplitude infrared variable stars ($\Delta K_{\rm s} >$ 1 mag) in 119 deg$^2$ of the Galactic midplane covered by the Vista Variables in the Via Lactea (VVV) survey. Almost all are new discoveries and about 50$\%$

In this chapter, we will be introduced to the six basic types of countermeasures - chaff, noise jamming, false targets, gate stealers, angle deception, and decoys. We will see how each is used, and learn how it is implemented and what its limitations

In this chapter, we will take a closer look at medium PRF operation. We will see what must be done to separate targets from clutter and how the signal processing is performed. We will then take up the problems of rejecting ground moving targets, elim

In the previous chapter, we examined the principal types of electronic countermeasures (ECM). We learned how each type is implemented and what its limitations are. In this chapter, we will examine some of the important electronic counter-countermeasu

In this chapter, the authors will consider what determines the amplitude of the ground return. The authors will then examine the doppler spectrum of each of the three categories of ground return, and the relationship of the composite spectrum to the

The advent of active ESAs, the emergence of low RCS aircraft, and the growing threat of electronic countermeasures have given impetus to advanced work in several key areas of radar technology. This chapter, presents some significant developments spaw

In this chapter, after briefly examining the problem, we will be introduced to two highly effective techniques for detecting such targets. One is called Classical DPCA, for displaced phase center antenna. The other and newer technique are called notc
