WebApr 10, 2024 · 1 INTRODUCTION. Target sensing with the communication signals has gained increasing interest in passive radar and joint communication and radar sensing (JCRS) communities [1-4].The passive radars, which use the signals that already exist in the space as the illumination of opportunity (IoO), including the communication signals, have … WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.
