Abstract: A portable radar simulator which when connected to a transmitting means s as a waveguide horn antenna provides a radar signal to test a radar receiver. The portable radar simulator comprises a tunable oscillator which generates a continuous wave signal in the microwave frequency range with the desired frequency of the signal being selected by an operator. The signal generated by the tunable oscillator is supplied to a microwave switch. The microwave switch receives a control signal provided by a pulse repetition frequency generating circuit and in response to the control signal turns the switch on or off controlling the transmission of the oscillator generated signal to the wave guide horn antenna. The pulse repetition frequency generating circuit which comprises an integrated circuit timer and a monostable multivibrator provides a variable frequency and variable pulse width control signal. The frequency and pulse width of the control signal are, in turn, set by the operator.

Abstract: An array of twenty corner reflectors with each corner reflector consisting f three mutually perpendicular reflecting planes whose intersection lie at a common point. The twenty corner reflectors are, in turn, configured to provide omni-directional reflection to incoming electromagnetic waves, while maintaining strong reflection characteristics.
